What estimating means

What estimating means

Three number lines showing 48.7 rounding to 50, 0.196 rounding to 0.2, and 431.1 rounding to 400 to one significant figure

Estimating means giving a sensible answer that is close to the exact value. In IGCSE questions, you usually round awkward numbers first so the arithmetic is quick and mental.
