About X-Mas Math

Numbers wear a disguise in this Christmas puzzle. In X-Mas Math, the four letters of XMAS replace digits, running from the thousands place down to the ones place: X first, then M, A and S. Take 3489 as an example, which would read X3, M4, A8, S9.

Your task is to use that code to solve each puzzle. It is a simple, fun brain teaser that trains number sense and logic, so it works well for school-age players. The mouse or a trackpad controls everything, and the page also loads on touchscreens.
