This question and many other similar questions such as 10 - 10 × 10 + 10 = ?, which I have also solve in other blog post has gone viral on social media and many people have answers like -15, 5, 25 etc. If you have been doubting your answer, then in this article I will solve and explain in details why the answer is -15 taking into consideration some Basic Mathematical rules such as :

Order of Operation (BODMAS and PEMDAS).

Solving from left to right.

Signs lies behind a number. This rules is affecting many answers so you have to take it serious and master your number line well.

Solution:

The solution to this question is simple but tricky. Many people always fall into the trap of not using basic mathematical principles and rules such as BODMAS and PEMDAS . BODMAS stands for:B=Bracket, O=Order of operation, D=Divison, M=Multiplication, A=Addition, S=Subtraction while PEMDAS stands for P=Parentheses, E=Exponents, M=Multiplication, A=Addition and S=Subtraction. So , using BODMAS,

5-5×5+5=?

First, multiply -5 × 5= - 25.

Remember in Maths a negative is attached behind a number not in front and if you multiply a negative number with a positive number your result should be negative. This is where you may get confuse .

Now 5 - 25 +5 = ?

10 - 25=? Recall that with BODMAS addition comes before subtraction and this really means you should deal with all the positives numbers in a question first wether the number comes after a negative number or not.

So, 10 - 25 = ?

- 15 = ? The answer is negative 15, use number line or a calculator to confirm your answer.
