It is 61: you do not need to estimate a sum as simple as that!
The answer is -30.
To estimate the sum of 56 and 58, you can round both numbers to the nearest ten. Rounding 56 to 60 and 58 to 60 gives you an estimated sum of 120. Therefore, the estimate of 56 plus 58 is approximately 120.
58 - 3 = 55 3 - 58 = -55
(7+4)5+3=58 (11)5+3=58 55+3=58 58=58
Other way round Not 3 / 58 It is 58 /3 = 19.3
58
c=61 - 3 =58
58/3 = 19 and 1/3
19.3333
Do this equation:(453/100)*58
3.8667
-3-58=-61, which is indeed negative.
