That's not the worst one. The worst one is when they dock you for showing the "wrong work", even when they acknowledge that the work you showed would still get the correct answer.

being good at math is a blessing and a curse

you can do it in your head but you forget to show your work

[ShimmeringVapidCoal]

The funniest part is that the test never explicitly stated you had to show your work.

Brilliant. This brings back some bad memories from my high school days. I had to do several exams over because I kept getting the right answers but always got points deducted for not showing my work, even when I did but they would say the work I showed was incomplete for “not drilling down far enough.” It’s also a stupid thing to teach kids. In real life, arriving to the right answer faster than everyone else with less effort is most certainly a plus not a negative.

I got my teachers to stop asking me to “show your work” WHICH I ALREADY DID by showing ALL THE WORK. Long division, vertical addition/subtraction, every minute detail we’ve long since been glossing over in algebra, written out in full. When I turned in that assignment, it was a pamphlet.

I was never told to show my work again.

This could actually be a cool concept for a villain, someone who commits crimes but is held back by the compulsion to explain to the heroes how he did it

[PaulGuy]

I showed my work and still got told it was wrong, because I didn't do it the way the teacher told us. Yet all of my answers were correct.

A teacher saying “show your work” is like a death sentence

[mr.x]

So relatable but don't even get me started on teachers and professors that fail you because you didn't format your work correctly despite you getting the right answers and proving that you understand the material.

I had this a lot in school. I could do almost all of it in my head, and I was never quite sure how much work was enough. I often got problems wrong because I apparently "didn't show enough."

Kinda similar to those dumb, "which of these items doesn't belong?" questions and similar. I could usually find commonalities among most or all of them in some way or another, and I never knew which was the difference they wanted. If I asked the teacher: "Okay, they're all fruits, even the tomato. One out of the five is not a berry. One out of the five isn't round. Out out of the five is a cool color (that is, not red, orange, yellow, or a variant thereof). One out of the five is fuzzy. One out of the five doesn't have an edible peel. One out of five doesn't have edible seeds. But all of the differences are on different items. Which one do you want?" They'd usually call me a smartass and give me a write-up or detention.

Last time I was asked to show my work, I just drew a picture of a human brain, and connected it to the answer with a thinking bubble.

When I was a freshman in high school (back in the late '80s), my teacher told me after class that we weren't supposed to use calculators on our homework. Puzzled at his statement, I told him I didn't use a calculator. The math wasn't particularly complicated, so I did it in my head. He looked me over for a second, picked up a piece of chalk, wrote out a problem on the board, then handed me the chalk. After about two seconds of thinking, I wrote the answer on the board. When the math was complicated enough that I needed to do it long form, I did. When it wasn't, I didn't, and just did it in my head. He was satisfied and never again mentioned it. He was a good teacher and a good human being.

Teachers like this made me go from loving math to hating it and falling behind because I lost interest in trying to prove myself

[reijikogarashi]

I remember when I was young, there was a girl who was doing a presentation to the class and the teacher basically stated that she didn't show her work. She replied him "You are supposed to already know how I got that answer. You're a teacher after all".

[caigetompkins]

That last one though with the baby. “NOPE, DOESN’T COUNT. YOU HAVE TO SHOW YOUR WORK!!” 😂😂😂

[TheNoodleGod]

THIS IS SO TRUE, BRO I HATE WHEN THEY SAY THAT.💀

[WillWonkeyTertel]

I remember I would get poor grades in math because I refused to use a page per problem to show my work because it would give my hands cramps.

Reminds me of the time I got into an argument with one of my math teacher over “showing my work”, apparently she didn’t understand how anyone could look at 9 squared and instantly know the answer. It took me going to the office and getting the teacher I had the year before to come in and explain how he had his students memorize the squares of 0 to 9 as an exercise for learning exponents. Got my points back and that teacher in particular got a talking to from the rest of the department about “lack of professionalism”, apparently I wasn’t the only student that got points taken off for that.

[gordonfurness]

My math teacher always wanted to see our work for every problem. There were several of us who protested this crazy requirement. He had a big discussion with us one day, and it was ultimately concluded that our everyday adult lives aren't going to involve worked-out math problems, and that showing our work for every single problem probably won't improve our math skills much. He stopped requiring us to show our work, but we were the only class that was allowed to do so, and we weren't allowed to alert other math students that we didn't have to show our work. He told us that each class had to "rebel" on their own and have the same kind of discussion we had with him. I don't think any of the other classes ever got out of having to show their work, but I wouldn't know since no one was allowed to talk about it, and if we did, the requirement would be put back into place.

How to do 81 + 1





1. Basic Addition: At its core, (81 + 1) is a straightforward addition problem. [ 81 + 1 = 82 ]This is the
simplest and most direct approach.2. Representation in Expanded Form:Let's express 81 and 1 in expanded form and then add: ( 81) can be expanded as (80 + 1). (1) remains (1).Now, add the components:[ (80 +
1) +1=80 + (1 + 1) =80 + 2 = 8213. Using Properties of Addition (Commutativity and
Associativity) :Commutative Property states that (a + b = b + a ).Associative Property states that ( (a + b) +
c = a + (b + c) ).Let's use both properties: [ 81 + 1 = 1 + 81 = 1 + (80 + 1) = (1 + 1) + 80 = 2 + 80 = 82]4.
Using the Number Line:Consider a number line from 0 to 100. Starting at 81:Moving 1 unit to the right will land you at 82.5. Binary Representation:Let's convert the numbers to binary and perform binary addition. ( 81) in binary: (1010001_2)(1) in binary: )Perform binary addition:[ 1010001_2 +
= 1010010_2 ]Convert ( 1010010_2) back to decimal:[ 1010010_2 = 82_{10} 16. Algebraic
Approach:Let ( x = 81) and (y = 1). Then (x + y = 81 + 1 = 82).7. Geometric Interpretation:If you were to
consider a square with side length 9 (since (81 = 9^2)), adding 1 to this could be visualized as increasing
the area by a unit square, although geometrically it doesn't change the square's dimensions.8. Using Modular Arithmetic:Consider the operation (81 + 1) modulo some number:For example, modulo 100:[ (81 +
1) \mod 100 = 82 \mod 100 = 82 19. Using a Recursive Sequence:Imagine a sequence defined as: [a_n =
a_ín-1} + 1, ltext{ with } a_0 = 81 ]Then:[ a_1 = 81 + 1 = 82 110. Calculus Context (for fun):Consider the
function (f(x) = x + 1) at (x = 81):[ f(81) = 81 + 1 = 82 ]Conclusion:Through various mathematical lenses,
the solution remains consistent: [ 81 + 1 = 82 ]
