👉 In computer science, a "backward" in a sequence of operations is an operator that performs the reverse of a given operation. For example, if you have a sequence of instructions like: ``` 1. Add 2 to x 2. Multiply x by 3 3. Subtract 4 from x 4. Divide x by 5 ``` Then you can say that the "backward" in this sequence is an operator that performs the reverse operation, which would be subtracting
