Probably easier to think of this the other way around as: 7 - 3 = 4.
10.
The sum of 3 plus 4 is 7.
the sum of 7 and 3 is 10
The sum is the answer to an addition problem. Example: 7 is the sum in the problem 3+4=7
Addends are the numbers that are added together to get a sum.
7
3 + 7 is an ADDITION sum
7(a+3)
The sum of 3 plus 4 is 7.
the sum of 7 and 3 is 10
7
The sum is the answer to an addition problem. Example: 7 is the sum in the problem 3+4=7
7+10=17 so the sum is 17. 10-7=3 so the difference is 3. Therefore, the two numbers are 10 and 7.
Addends are the numbers that are added together to get a sum.
3(y+7)
3*(t + 7) or 3t + 21
7+3+10 = 20
2 + 2 + 3 = 7
