Algebraic Substitution (1 of 2: What does it mean?)

Like your teaching method of grabbing students attention with an interesting topic of basketball and then segueing into the math. Great stuff, #Respect !

Haha I'm doing first year physics right now and I didn't even know that we called them pronumerals. Thanks for this one, looking forward to the next one.

Gru is the most powerful being in the universe, and here’s why: according to the height of a Minion (which is 3.5 feet on average) Gru is 4 minions tall, which means he is a godly size of 14 feet tall. Second if any of you remember the original Despicable Me, you Know there is a scene when Vector kidnaps the three girls and shoots a series of heat-seeking misses at Gru, he then dodge them all. According to the speed of an average ballistic missile (1900 mph) and the size of the missile according to his ankle size, Gru can perceive and move at such a speed that the missiles only move 9.5 miles per hour, 0.5% of their original speed. Plus after this Gru punches a shark and it is paralyzed meaning its spine is probably shattered, to remind you it would require a force greater than 3, 000 newtons to fracture the spine. That’s equal to the impact created by a 500-pound car crashing into a wall at 30 miles per hour. I rest my case.

If we write the circle's area as the radius squared multiplied by pi, we would write the area in terms of pi.

Pi, is not a pronumeral as it has a fixed value. Pronumerals values can be different in different problems. Sorry for the negative comment

"I won't ask you to recite all of pi, we'll be here forever" heehee

[kamesenin]

The radius is 15, just like that ? 15 cm ? 15 liters ? 15 Pascals ? 15 chewing gums ? They must get used to putting units in there. Sorry for the criticism, I can’t help.
