can you guys plz help me???? p.s can u show the work

0.796 + 13 = 13.796 (the 13 is a whole number, so just put it in front of the decimal)

15.63 + 24.36 = 39.99 (1+2=3 ; 5+4=9 ; 6+3=9 ; 3+6=9)

19.86 - 4.94 = 14.92

82 - 67.18 = 15.18 (again, whole number, there's no decimals to subtract, so leave them be)

14.39 - 12.16 = 2.23 (1-1=0 ; 4-2=2 ; 3-1=2 ; 9-6=3)

To add or subtract decimals, align the decimal points and perform the operation while observing significant figures. Round the final answer based on the least number of decimal places in the input numbers. For example, 56.0 + 3.44 = 59.4 after rounding to one decimal place.
