5 - 5 =
Explanation
When subtracting 5 from 5, we are essentially taking away 5 from a group of 5. Since there are no remaining objects in the group after the subtraction, the result is 0.
11.
4 - 4 =
Explanation
The subtraction of 4 from 4 results in 0. When two numbers are subtracted and they are equal, the result is always 0. In this case, both numbers are 4, so subtracting 4 from 4 will give 0 as the answer.
12.
3 - 0 =
Explanation
The subtraction of 0 from any number is always equal to the number itself. In this case, when 0 is subtracted from 3, the result is 3.
13.
3 - 1 =
Explanation
The question is asking for the result of subtracting 1 from 3. When we subtract 1 from 3, we are taking away 1 unit from 3, which leaves us with 2 units. Therefore, the correct answer is 2.
14.
2 + ___ = 5
Explanation
To find the missing number in the equation, we need to determine what number, when added to 2, equals 5. In this case, the missing number is 3 because 2 + 3 equals 5.
15.
3 - 3 =
Explanation
When subtracting a number from itself, the result is always zero. In this case, subtracting 3 from 3 means taking away 3 from a group of 3, leaving no remaining items. Therefore, the answer is 0.
