Answer 1

Wow! That looks like it could be your whole assignment!! Adding and subtracting decimals is just as easy as with whole numbers. Just line up the decimal points and add up or subtract the place values that line up! You don't need someone to give you all the answers....

Answer 2

Dude, we're not gonna do your homework, but i'll explain to you decimals. You add the decimals in their proper place values, for example 4 is a whole number which means it goes to the left of the decimal point. Then you continue to add the numbers in their proper location. When addint always remember to move the decimal place on the final answer the number of decimals that each number added or subtracted have.
