Go MathsLearning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those.

To convert a number to standard form means to write it in the form a x 10^{b} where a is a number greater than or equal to one and less than ten and b is an integer.
34800
= 3.48 x 10000
= 3.48 x 10 x 10 x 10 x 10
= 3.48 x 10^{4}
0.0348
= 3.48 ÷ 100
= 3.48 x ^{1}⁄_{100}
= 3.48 x 10^{2}
Finally note that any number raised to the power zero is 1 so:
3.48
= 3.48 x 1
= 3.48 x 10^{0}
