$${\mathtt{100}}{\mathtt{\,\times\,}}{\mathtt{33\,333}} = {\mathtt{3\,333\,300}}$$
Hey Maddy you should join the Forum
$${{\mathtt{7}}}^{{\mathtt{2}}}{\mathtt{\,\small\textbf+\,}}{\frac{{\left(-{\mathtt{2}}\right)}^{{\mathtt{3}}}}{{\left(-{\mathtt{2}}\right)}^{{\mathtt{2}}}}} = {\mathtt{47}}$$
It's not that hard if you study it.
a²+b²=c²
12²+b²=20²
144+b²=400
√256=16
