1. 12.83 + 16.24 = 29.07
2. $26.92 + 9.41 + 3.82 = $40.15
Okay on these two problems all you need to do is add, adding is quite simple but if your ever having trouble on adding, subtracting, dividing etc, then look up or find a calculator. Calculators are very helpful, especially on problems like this. If you need more help just ask.
