# What is the scientific notation for 100?

The scientific notation for 100 is $1 \times {10}^{2}$ This comes from the fact that in the number 100, the decimal point is after the second zero, and to put this number into standard form, you must move the decimal point backwards two places, giving you $1.00$, which, if you then move the decimal point forwards two places, gives you $100$.
Standard form is a way of writing numbers in short, which is easier than writing large numbers, such as one million, which, in standard form, is $1 \times {10}^{6}$.
