Step-by-step explanation:

no calculator available ?

this is pure number typing. no problem to be solved, no trick or hidden meaning to be considered, nothing.

at least the way you were typing the "problem" definition. as there are clearly some issues with the phrasing, maybe something was missed.

but here it goes :

61.2 + 9.35 + 8.6 = 79.15 meters

9.44 - 2.11 = 7.33 meters

1.36 + 10.17 = 11.53 meters

34.61 - 17.3 = 17.31 meters

The solution to the operations are:

a 79.15 meters

b. 7.33 meters

c.11.53 meters

d. 17.31 meters

This '+' is the addition sign. For numbers that have this sign, add the numbers together. This '-' is the subtraction sign. For numbers that have this sign, subtract the numbers from each number.

In order to round off to two significant numbers, the numbers after the decimals should be two non-zero digits.

a 61.2 meters + 9.35 meters +8.6 meters = 79.15 meters

b. 9.44 meters - 2.11 meters = 7.33 meters

c. 1.36 meters + 10.17 meters = 11.53 meters

d. 34.61 meters - 17.3 meters = 17.31 meters
