Start with . That gives . Write the ones' place down underneath the and the and carry the to the next place.

Next, do . That gives . However, remember to add the you carried over from the previous step.

Now, write down down next to the . Make sure the is lined up beneath the and and the is in the hundreds' place.

Now, do . Because we are multiplying using the tens' place of , you need to make sure that you write down the product of and in the tens' place, underneath the from your previous answer.

Next, do . Write this product () in the hundreds' place.

Finally, add these two numbers together.

.

Use a calculator to check your work if allowed, but if not, then I'd reccommend the following method, breaking the problem down into smaller pieces.

And then add your results:

To solve this equation, follow order of operations:

First we do the calculations inside the parentheses.

Then we subtract to get our final answer.

You can simplify this problem:

, and , so if you simplify those parts of the equation, you are left with .

.

We can see this by implementing objects.

groups of objects

^ We can see that there are 21 objects.

To solve for m we need to isolate m on one side of the equation and all other numbers on the other side of the equation.

Our first step is to divide by 12 on both sides. Remember to undo an operation from one side of the equation and cancel out a number we need to perform the opposite operation. If you have a number multiplied by another number or a variable you need to divide to cancel out that said number.

Then we divide by 3 to get our final answer.
