Worksheet Overview

QUESTION 1 of 10

 

In this worksheet, you must decide whether the answer to an subtraction is odd or even.

 

Example

Is the answer to this subtraction odd or even?

37 - 15

 

Answer

37 - 15

 

We just look at the units digits and subtract 7 - 5 = 2, which is even.

Remember that odd numbers end in 1, 3, 5, 7 and 9.

Even numbers end in 0, 2, 4, 6 and 8.

 

So the answer is even.

Alternatively, you could simply work out 37 - 15 = 22, which is even.
