Written mathematically is would look like:
(10+4) - 6
14 - 6 = 8
46
x+10>13 it wouldn't be x+10-13 ??
The sum of the composite numbers that are less than 8 is: 4+6 = 10
According to the numerical puzzler, Digit total means adding up the digits in the number and then seeing if it is less than ten. Eg. 1111 = 1+1+1+1 = 4 and so is less than 10. 76 would be 7+6 = 13 and so would not be less than 10. Hope this helps?
i think the anwer is 78
The sum of all prime numbers less than ten is 17. Pick a number 18 or higher.
26
The sum of the five odd numbers between 10 and 20 is: sum = 5 x (11 + 19) / 2 = 75.
37 3+7=10
The number is thirty-seven.
It is: 2+9 = 11
x + (13-10)
37
2 is the smallest prime number. 9 is the greatest composite number less than 10. The sum of 2 and 9 is 11.
46
80
The sum of the factors of 10 (excluding itself) is equal to 1 + 2 + 5 = 8. Therefore, since its factor sum is less than the number itself, 10 is a deficient number. The lowest abundant number is 12.
