Standard Form: Multiplication, Division & Without Calculator

This lesson builds on standard form addition and subtraction, focusing on multiplication and division: multiply coefficients and add powers, divide coefficients and subtract powers. It also covers “without calculator” style problems common in WAEC/NECO/JAMB, where messy decimals must be converted to standard form first before simplifying. Practice includes clean standard-form values, decimal expressions, and combined multiply-then-divide problems.
