Answer:

Step-by-step explanation:

23 - (-2)

= 23 + 2

= 25

1) The mistake you made was to subtract 2 from 23 instead of  subtracting -2 from 23.

2) Keep in mind the difference between the '-'  used as a subtraction and the '-' used for indicating a negative number.

If you like, remember the mantra ' 2 negatives make a '+'.:-

2 - -4

= 2 + 4= 6.
