Number warm-up

Almost every Digital SAT Math question uses basic arithmetic. A slip with a fraction or a lost minus sign can cost you a point even when you understood the problem. So we warm up first.

We go one idea at a time: order of operations, fractions, negative numbers and exponents. Each one has animated pictures that show why the rule works, a quiz after each part, and practice questions. It is a good base if you want to prepare for the SAT Math section on your own. Go slowly, and repeat any part you need.
