Week 18: Lesson 1

25 decreased by 5 uses subtraction because "decreased" means something became less or smaller

"Sum" means addition

"difference" means subtraction

"product" means multiplication

"triple" would mean 3 times as much, so that's multiplication

"product" is the word used to describe the answer in a multiplication problem

the word "twice" means do something two TIMES, so that's multiplication

"reduced" means something became smaller or less, so that's subtraction

The "product" means the answer to a multiplication problem; a "quotient" is the answer to a division problem; "decreased" means you have less, so that's using subtraction, the "total" is the answer to addition, and "taken" means you don't have it now, so that's subtraction.

"difference" means subtraction

The phrase "less than" switches the order, so the n has to come before -10.

Quotient means the answer to a division problem.

We use the fraction bar to show division when we are doing algebra.

The product is the answer to a multiplication problem

We do NOT use X to show multiplication in algebra. We just write the number and then the variable (the letter) with nothing in-between (there's an invisible multiplication sign in between the number and letter!)

Less means subtraction. The word "than" switches the order in the expression. So instead of it being 6 - k, they trade places and it becomes k - 6.

"Difference" means subtraction so it has to be 10 - 3. There were no reversing words (than or from)

The end....thank you for your work!
