This is the second of our difficult quizzes on addition and subtraction. Like the previous quiz, it will give you a chance to practice adding and subtracting decimals. This may sound daunting at first, but it really is just the same as working with whole numbers – just make sure you know where to place that decimal point!
As you should be used to by now, when adding and subtracting any number, first work with the largest set of numbers (1,000s, 100s etc.), then the second largest (100s, 10s), then continue through the lower numbers (ones, tenths, hundredths etc.).
It’s a good idea to have an estimate of the final answer – if nothing else, it will help you place the decimal point where it belongs!
