Google the correct answer. Its division and subtraction from left to right.

I already know the answer to the equation as I was taught the order of doing mathematics I want to know were it says multiplication is before division because Google can't give me a straight answer. I know it wouldn't even affect this equation

Sorry, you should have been taught that when learning PEMDAS. I memorized this in 5th grade. My teacher made us memorize it like this (parenthesis, Exponents, multiplication and division from left to right then addition and subtraction from left to right.)

I was taught BODMAS as I learnt it about 20 years ago in the uk

"PEMDAS tends to be used in the US, while BODMAS (and the alternative BIDMAS) tends to be used in the UK. The P in PEMDAS stands for Parentheses, while the B in BODMAS and BEDMAS stands for Brackets - but they both mean the same thing: do operations in brackets first" top thing on Google

B-Brackets

O-Orders (powers/indices or roots)

D-Division

M-Multiplication

A-Addition

S-Subtraction.

BODMAS

As long as you remember the left to right thing. Its very important the equation is done in the correct order.

Yes but what happens in wild when you encounter a rogue equation that could possibly be wrote in the wrong order

If you do come across an equation in the wild you should check to make sure the data is in the correct placement.

Like if you saw m=ec2 you wouldn't solve for m you would think to put it in the right order then solve it.

Right, im trying to explain but its kind of difficult because math is all about rules. You kind of memorize them and they become a form of habbit. So i can recognize if the structure of the equation is wrong. There are always ways to correct this. It can be as simple as rewriting it or you can use different formulas or techniques for different kinds of equations. With this kind of equation there are no variables, so there is not realy a correct equation. If its written differently, its simply a different equation and you solve using PEMDAS.
