Question

Solve & Explain your Math thinking 12-7

Answer 1

For this case we have the following subtraction:

$12-7$

We can rewrite the subtraction in an easier way.

We have then:

$12-7 = 12 - (5 + 2)$

Then, by doing associative property we have:

$12 - (5 + 2) = (12-2) - 5\\(12-2) - 5 = 10 - 5\\10 - 5 = 5$

Answer:

The value of the subtraction is given by:

$12-7 = 5$

Answer 2

The answer is 5 because I used an example to get my answer. The example I used was "Anna had 12 slices of apples, and she ate 7 slices. How many slices she have left?" That is my example to help for my answer. Another way is to draw 12 things, like pieces of candy, and cross out 7 pieces of candy, then count how many pieces of candy I haven't cross out.
