if your trying to find the sum of 37=58 the steps would be:

Units - 7+8=15
Tens - 30+50=70
= 70+15 = 85

Answer:

To sum 37+58 mentally, we could first sum 30+50=80 and then sum the units, 80+7+8= 95.

But, if we have to show properties, we could separate first the numbers:

30 + 7 + 50 + 8.

Then, we apply commutative property to position like numbers aside:

30+50+7+8

Then, we apply associate property, to have a better order of the operation, which is easier to the mind:

(30+50) + (7+8)

Then, we sum each group:

80 + 15

At last, we sum again and have the result:

80+15=95.
