Test: Addition - 1 - Grade 4 MCQ

The sum of numbers being added is always greater than the individual numbers being added, except when one or more of the numbers being added is zero. In that case, the sum will be equal to the non-zero numbers being added.

If  we change the order of the numbers being added the sum does not change.
(Property of addition)
i.e., a + b = b + a

When you add zero to any number, the sum will always be equal to that number. So, in this case, 0 + 33 equals 33.

If we add zero to any number, the sum remains the same (Property of addition)

When you add one to any number, the sum is always its successor. For example, 1 + 1 equals 2, 5 + 1 equals 6, and so on. Therefore, the sum of any number plus one is always its successor.

When you add 1 to 25, the sum is 26. Therefore, 25 + 1 equals 26.

We know addend + addend = sum

When you add 43 and 32, the sum is 75. Therefore, 43 + 32 equals 75.

Sum, Plus and Increase will be the increment of the number,

but the difference will decrease the number.

On adding two numbers the result obtained is called sum.
