The sum of 3 plus 4 is 7.
-3.
The sum is the answer when you have added. ex. 2+3, the sum is 5.
if the sum of three is six then it would be 30 right?? i think depends on wat sum of 3 is
Check the sum of the digits, if the sum divisible by 3 then the number is divisible by 3. Example 910: the sum of digits= 9 + 1 + 0 = 10, but 10 is not divisible by 3, so the number 910 is not divisible by 3. Example 2154: the sum of digits = 2 + 1 + 5 + 4 = 12, this sum is divisible by 3, so the number 2154 is divisible by 3. if the sum is long you can check the sum of the sum and apply the same rule. Example 52498731: the sum of digits = 5 + 2 + 4 + 9 + 8 + 7 + 3 + 1 = 39, the sum of the digits for 39 = 3 + 9 = 12, so the original number, i.e. 52498731 is divisible by 3.
20 + 3 = 23
11. Sum means to add 3+8=11
the sum of 3 times m and n
The sum of xy times 3 is equal to 3(xy).
3 + 7 is an ADDITION sum
The sum of 3 plus 4 is 7.
