S Calculating in the

wrong order will give you

a wrong answer! "Operations" means things like

add, subtract, multiply, divide, square, etc.

The "order" is the order in which you

do these operations. When you see something like ...

7 + (6 × 52 + 3)

... what part should you calculate first?

Start at the left and go to the right?

Or go from right to left? M

E A D D or or S U B T R A C T Long ago, people came up

with the solution to this problem

so there would be no confusion.

The solution is called

the order of operations. Distribute the exponent (a.k.a. power)

to the base before you

multiply or divide. Don't forget that roots are exponents! Multiplication and division are on the same level.

You can solve them at the same time.

Just remember to do it left to right. Addition and subtraction are also on the same level.

You can solve them at the same time.

Just remember to do it left to right. 2×10+(4) -4+6÷2 2 2×10+16-4+6÷2 2×10+16-4+6÷2 20+16-4+3 20+16-4+3 =35 Example: This is how I would

introduce this

math skill to my

elementary class. This can be hard to remember,

so here is a trick you will

remember every time! ...or you can create your own.

It doesn't really matter how

you remember it, just so long

as you get it right. Works Cited:
