Most of the examples and exercises in these lessons deal with only two terms at a time. However, you don't have to advance much further in your study of mathematics--and algebra in particular--until you encounter situation where you must multiply and divide strings of three or more signed integers. For instance:
(+ 4) x (+ 5) x (+ 12) x (+ 6) = _____
(+ 12) x (– 10) ÷ (– 8) = _____
(+ 72) ÷ (+ 16) x (– 2) = _____
(+ 17) x (+ 24) ÷ (– 1) x (+ 6) = _____
