+109 Scientific Notation is just moving decimals around while maintaining the consistency of the number. It's manipulating large or small numbers with powers of ten. Multiplying a number by ten shifts a decimal place to the right, similarly dividing shifts a decimal place to the left.
$${\mathtt{24.91}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{1}}} = {\mathtt{249.1}}$$
$${\mathtt{24.91}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{0}}} = {\mathtt{24.91}}$$
$${\mathtt{24.91}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{-{\mathtt{1}}} = {\mathtt{2.491}}$$
To know which way to shift the decimal is solely reliant on the power of ten.
$${\mathtt{1}}{\mathtt{\,\times\,}}{{\mathtt{10}}}^{{\mathtt{X}}}$$
Should X be positive then the decimal will shift X places to the right, otherwise X is negative and should be shifted X places to the left.
Hope this helps.
