I don’t really know but try a calculator

You must use PEMDAS. In this case, you only have multiplication and subtraction. Multiplication comes first. 3.97x10 = 39.7 and 3.31x10 = 33.1. Now replace this information: 39.7 - 5 - 39.1 - 5. Now work left to right and subtract. 34.7 - 39.1 - 5. -4.4 - 5. -9.4.
