The answer is -30.
60 and 25 = 85
25 and 33
It is 61: you do not need to estimate a sum as simple as that!
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.
The numbers are: 37.5+20.5 = 58 and 37.5-20.5 = 17
92 and 34
The two numbers whose sum is 58 and whose difference is 16 are 21 and 37.
The sum of two numbers between 20-40 is 58. The difference is 12
33+25=58 32+26=58 14+44=58 etc......
65 + 58 = 123 65 - 58 = 7 The two numbers are therefore 58 and 65.
The sum of 37 and 58 is 95.
