sq

→ sq()

Multiplies a number by itself — `sq(3)` is 3 × 3, which is 9.

sq(palo)

sq(3) is 9. sq(-3) is also 9, because two numbers below 0 multiplied together give a number above 0. So the result of sq is never below 0.

The name is left as it stands. sq is the short form of “square”, a piece of mathematical notation rather than an everyday word. In Botswana, mathematics is taught in English from the upper grades onward, and the notation a learner meets in class is the notation used here. See sqrt and pow, which travel with it.

Writing palo * palo is just as good — sq saves you repeating the variable name.
