To find out what number needs to be subtracted from 23 to result in 16, we can set up a simple equation. Let’s call the number we are looking for ‘x’. The equation will look like this:
23 – x = 16
To solve for ‘x’, we can rearrange the equation. We want to isolate ‘x’, so we can subtract 16 from both sides:
23 – 16 = x
Calculating the left side gives us:
7 = x
So, the number that should be subtracted from 23 to get 16 is 7. In other words, if you take 7 away from 23, you are left with 16.
