Question

Jean adds 35 and 9. how can she solve using only equations to model her thinking?

Answer 1

She can break up the nine in to 3 three time and add it to 35

Answer 2

Answer: Required value is 44.

Explanation:

Since we have given that

there are two numbers 35 and 9.

We need to add it using only equations to model.

First we split 35 into 30 and 5:

`35=30+5`

then we add it to 9, to get the answer:

`(30+5)+9`

then, we will use the "Associative property", which says that

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

`(30+5)+9\\\\=30+(5+9)\\\\=30+14\\\\=44`

Hence, required answer is 44.
