Answer:
She will need to subtract 47 from 97, resulting in her answer being 50.
Joylin needs to add 4 to the answer 50.
The given statements are :
Joylin is subtracting 43 from 97.
She adds 4+43 before subtracting.
We need to know what to do with the answer we get after subtracting
4 + 43 from 97 instead of 43 from 97.
We see that the real calculation Joylin needs to do is to subtract 43 from 97.
Joylin added 4 with 43 and subtracted with 97 so we have,
4 + 43 = 47
Subtracting 47 from 97.
we get,
97 - 47 = 50
But the real calculation that needs to be done is:
97 - 43 = 54
So we have a difference between the calculation that needs to be done and the calculation done.
The difference is 54 - 50 = 4.
So in order to do away with the mistake Joylin did by adding 4, Joylin needs to add 4 with the answer i.e 50 so that we get the same answer as the answer i.e 54 in the real calculation.
Thus, Joylin needs to add 4 with the answer 50 so that the answer is the same with 97 - 43 = 54.
