Number: N1 Adds

How good are you at adding up? Find out here! You will find that there are six sets of questions to try, which get gradually more difficult! In each case you must add up a column of numbers. Don't use a calculator! Start with Set 1.

To get started, move the cursor to the first blue cell, enter your answer and then press the Enter key (or move to the next cell). You will be told if your answer is right or wrong. Work down the spreadsheet from Set 1 to Set 2, and so on.
