You know that 37 subtract 24 equals
13. Is it true that 13 plus 24 equals
37?
In this question, we’re told that
37 take away 24 equals 13. 37 is the whole amount that we
start with. We subtract 24, and we’re left with
13. 37 is the whole amount, and the two
parts are 24 and 13. We’re asked if it’s true that 13
plus 24 equals 37. What do you notice about these
three numbers? We have the same three numbers in
our addition calculation, as we do in our subtraction calculation. 37 is the whole amount that we
started with. We subtracted 24, and we were left
with 13. So, 13 plus 24 equals 37.
We can quickly check this
calculation to make sure that it’s true. Let’s start by adding the ones. Three ones and four ones makes
seven ones. We know that’s correct. Let’s just add in the tens
column. One 10 plus two 10s equals three
10s. It is true that 13 plus 24 equals
37.
