2. Verify associative pro​

Answer 1

Explanation:

The associative property comes from the words "associate" or "group." It refers to grouping of numbers or variables in algebra. You can re-group numbers or variables and you will always arrive at the same answer.

This equation shows the associative property of addition:

(a + b) + c = a + (b + c)

(2 + 4) +3 = 2 + (4 + 3)

This equation shows the associative property of multiplication:

(a × b) × c = a × (b × c)

(2 × 4) × 3 = 2 × (4 × 3)

In some cases, you can simplify a calculation by multiplying or adding in a different order, but arriving at the same answer:

What is 19 + 36 + 4?

19 + 36 + 4 = 19 + (36 + 4) = 19 + 40 = 59
