Standard Form - OCR GCSE Maths Lesson

What standard form means

$Worked diagram showing 64800000 changing to 6.48 times 10^7 and 0.000731 changing to 7.31 times 10^{-4}, with decimal moves labelled$

Standard form writes a number as $\times 10^n$ . The coefficient $a$ must satisfy $\le a < 10$ , and $n$ must be an integer, so it can be positive, negative, or zero.

Step-by-step lessons covering OCR GCSE Maths Standard Form for Foundation and Higher tier. Each lesson works through exam-style questions in the written papers format. Build fluency with number, ratio and algebra first, since geometry, probability and statistics topics rely on them, and leave extra time nearer the exam for Higher-tier problem-solving and multi-step reasoning questions.
