Here are four expressions that have the value
= 1 + 2 2 2
-2x - 4
- 1+2
Enter five expressions: a sum, a difference, a product, a quotient, and one that involves at least two
operations that have the value

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
