-0.75 - (-2/5) + 0.4 + (-3/4) ok, so there are negative numbers that are being added and subtracted, which is needlessly complicated. Let's simplify that. - (2/5) is a fancy way of saying "take away negative 2/5", which means "ADD 2/5". if you see a negative number being REMOVED, you want to add the number as a positive.  with + (-3/4), you ADD negative 3/4, which is just taking away 3/4.  Here's the problem re-written, -0.75 + 2/5 + 0.4 - 3/4   That's a lot simpler, but it's still a bit confusing because there are both fractions and decimal numbers. To find the decimal version of a fraction, divide the top number (the numerator) by the bottom number (the denominator).  2/5 = 2 divided by 5 = 0.4 3/4 = 3 divided by 4 = 0.75 here's the new question: -0.75 + 0.4 + 0.4 - 0.75 -0.75 + 0.4 + 0.4 - 0.75 = -0.7
