The order of operations says we have to do multiplication before addition. A good way to remember the order of operations is to remember "PEMDAS."

So you do parenthesis first, then exponets, then multiplication & division, (whichever comes first) then addition & subtraction (whichever comes first)

Here's how you'd work it out.

Yes Ninja,  it is easier to take things in if they are well presented.

This is beautiful.  

Since you are only 14 I don't think that you have missed anything just yet!

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{60}}{\mathtt{\,\small\textbf+\,}}{\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{9}}{\mathtt{\,\small\textbf+\,}}{\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}}$$

You have to use the order of operations to do this problem.

An easy way to remember it is PEMDAS, or PEDMAS.

PEDMAS = Parentheses, Exponents, Division, Multiplication, Addition, & Subtraction.

PEMDAS = Parentheses, Exponents, Multiplication, Division, Addition, & Subtraction. 

Now let's multiply the question one by one.

$${\mathtt{3}}{\mathtt{\,\times\,}}{\mathtt{60}} = {\mathtt{180}}$$

$${\mathtt{5}}{\mathtt{\,\times\,}}{\mathtt{9}} = {\mathtt{45}}$$

$${\mathtt{2}}{\mathtt{\,\times\,}}{\mathtt{2}} = {\mathtt{4}}$$

Now that we got everything, let's add it.

$${\mathtt{180}}{\mathtt{\,\small\textbf+\,}}{\mathtt{45}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}} = {\mathtt{225}}{\mathtt{\,\small\textbf+\,}}{\mathtt{4}} = {\mathtt{229}}$$

So, our final answer is $${\mathtt{229}}$$.

It is simple as that.
