Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician? Comment recorded on the 3 October 'Starter of the Day' page by Mrs Johnstone, 7Je: "I think this is a brilliant website as all the students enjoy doing the puzzles and it is a brilliant way to start a lesson." Comment recorded on the 23 September 'Starter of the Day' page by Judy, Chatsmore CHS: "This triangle starter is excellent. I have used it with all of my ks3 and ks4 classes and they are all totally focused when counting the triangles."

Standard form, also known as scientific notation, is a way of conveniently writing numbers that accommodates values too large or small to be conveniently written in standard decimal notation.
3.48 x 10^{4}
= 3.48 x 10 x 10 x 10 x 10
= 3.48 x 10000
= 34800
3.48 x 10^{2}
3.48 x ^{1}⁄_{100}
= 3.48 ÷ 100
= 0.0348
Finally note that any number raised to the power zero is 1 so:
3.48 x 10^{0}
= 3.48 x 1
= 3.48
