i have to estimate each product or quotient are these right?
-72 x 57 i got:
-70 x 60 - -4200
-92 x (-41) i got
3600
-83 x 52 i got:
-80 x 50 = -40000
-803 x (-106) i got
-800 x (-100) = 80000
49 x 61 i got 50 x 60 = 3000

I agree with your estimates.
For this one, I'd find a multiple of 90
476 = 450
450/90 = 50
Do the same for the others.

SO IT WOULD BE -476 / 90
ESTIMATE IS -450 / 90 IS -5
IM NOT UNDERSTANDING ESTIMATE FOR
538/ (-63)
479 / (-61)
