-13 is the number must you subtract from -13 to get a difference of 0
2
3
The difference between 13 and 16 is 3. To find the difference between two numbers subtract the larger number by the smaller number. (16-13=3)
To subtract a negative number, you must change the subtraction sign to an addition sign, then make the second number its opposite. Ex. (-9)-(-13) (-9)+(+13)=4
70 - (20 - 13)
The number must meet two criteria:Take the original number excluding its last digit and subtract two times the last digit from it. The result must be divisible by 7.Take the original number excluding its last digit and subtract nine times the last digit from it. The result must be divisible by 13.In both cases, you can repeat the "truncate-and-subtract multiple" stage several times, if required.
Correct.

n + 20 - 17 + 13 - n = 20 - 17 + 13 = 3 + 13 = 16
70 - (20 - 13)
Correct.

When you are presented with a set of data and you need to find the range, you must subtract the lowest number in your data set from the highest number in the data set provided. For example, you are presented with this data set and you must find the range of the data. 34, 82, 43, 13, 14 You have to subtract the lowest number (13) from the highest number (82) so the range of this data set is 69. If you want to find the range you look at your data. Then you find the maximum number and the minimum and you subtract the two. Then you have your range.
25. work backwards. take 37 ADD(instead of subtract) 13 to it. then take 50 and divide it by two.
Using algebra the number works out as 25
Subtract 1999 from it.
13 - 12 = 12
Do you mean the difference? The difference is 13.
