(-23) + (-13) = -36
You are adding a negative quantity to another negative quantity, so the sum is more negative than the two addends.
13 + 23 + 12 + 7 = 55
23 plus 69 plus 13 plus 3 percent of 100 percent = 108 = 23 + 69 + 13 + 3 * 100% = 23 + 69 + 13 + 3 = 108
11m + 13 = m + 23 10m + 13 = 23 10m = 10 m = 1
36 + 23 = 59
-23
10 and 13
The sum is 93.
M+23
98
The sum of 23 and 13 is 36
