How do i do 19-24? can someone me

the answer is -5

step-by-step explanation:

you need to do the rest as a normal rest:

  19

- 24

the only difference is that you do not have enough values to rest 24.

so the result is how many you need to complete the rest of 24, now you have 19, and you need 5 more to rest 24.

this 5 that you need is a negative number since you do not have it, that is why the answer should be presented as negative number.

remember that the result of any mathematical operation not always is going to be a positive number.
