Let the number be x and so 3x+10-2x which can be simplified to x+10
My number is 11.
-1,-2,+2,-4,+4,-5,+5, +0. the sequence is subtract twice, add once, subtract again, add, then subtract, then add twice.
-5+-3 = -8 ++ Add -- Add +- Subtract -+ Subtract
If the number has a + sign then you add it, if it has a - sign, then you subtract it.
The inverse operation for subtract 5 is add 5. This is because whatever number you start with, if you first "subtract 5" and then "add 5" or if you first "add 5" and then "subtract 5" you are back to the number you started with.

Subtract and add the sign of the greater number.
You have to add the additive inverse. To subtract q, you add -q.
-5+-3 = -8 ++ Add -- Add +- Subtract -+ Subtract
Any four-digit number will do. Add it to the number 33333, to get the original number you have to subtract from.Any four-digit number will do.

Number. You need a number.
3x-7+4 = 42 3x-7 = 38 3x = 45 x=15
Yes.
If you want to use a number line to add and subtract, it can be done with a slide rule. But it is much easier to use an electronic calculator.
