The reverse of subtracting 849 is adding 849. In mathematical terms, if you have an expression like x - 849, the inverse operation is x + 849, as addition undoes the effect of subtraction.
The reverse of subtracting 849 is essentially adding 849. The operation of subtraction is the inverse or reverse of addition. When you subtract a number, say 849, from another number and want to reverse that operation, you add 849.
Mathematically, if you have an expression like x - 849, the reverse or inverse operation is x + 849. This is because adding 849 undoes the effect of subtracting 849. In symbolic terms, the reverse operation of a - b is a + b.
So, if you have the instruction to reverse the operation of subtracting 849, the result is to add 849. For example, if you reverse the subtraction of 849 from 1000, the result is 1000 + 849, which equals 1849.
