So, starting at 3:
Adding 1 to 3 gives you 4.
Adding 1 more to 4 gives you 5.
Adding 1 more to 5 gives you 6.
Adding 1 more to 6 gives you 7.
Adding 1 more to 7 gives you 8.

When you subtract 5 from 9, you are finding out how many are left after taking 5 away from 9.
So, starting at 9:
Taking away 1 from 9 gives you 8.
Taking away 1 more from 8 gives you 7.
Taking away 1 more from 7 gives you 6.
Taking away 1 more from 6 gives you 5.
Therefore, 9 - 5 equals 4.

When you subtract 3 from 10, you are finding out how many are left after taking 3 away from 10.
So, starting at 10:
Taking away 1 from 10 gives you 9.
Taking away 1 more from 9 gives you 8.
Taking away 1 more from 8 gives you 7.
Therefore, 10 - 3 equals 7.

True or False? 3 + 6 = 8
Correct Answer
B. False
Explanation
To determine if 3 + 6 equals 8, you need to add the two numbers together.
So, starting at 3:

Adding 1 more to 6 gives you 7.
Adding 1 more to 7 gives you 8.
Adding 1 more to 8 gives you 9.
Therefore, 3 + 6 equals 9, not 8.
So, the statement 3 + 6 = 8 is False.
