Order of Operations with Parentheses

Apply the distributive property and proceed to multiply each term inside of the parentheses by 187:

$187\times8-187\times5=$

Solve the first multiplication problem vertically, making sure to solve it in the correct order (ones multiplied by ones, ones multiplied by tens, ones multiplied by hundreds )

$187\\\times8$

We should obtain the following result: 1496

Proceed to solve the second multiplication problem vertically, once again making sure to solve it in the correct order (ones multiplied by ones, ones multiplied by tens, ones multiplied by hundreds )

$187\\\times5$

We should obtain the following result: 935

Now to tackle the next problem:

$1496-935=$

We should once again solve this vertically. Make sure to align the digits properly, ones under ones, tens under tens, etc.:

$1496\\-935$

Subtract ones from ones, tens from tens, etc., to obtain the final result: $561$

First, calculate the expression within the parentheses:

$2 \times 1 = 2$

Now, multiply the result by 9:

$9 \times 2 = 18$

Thus, the final answer is 18.

First, solve the expression inside the parentheses:
$10 + 7 = 17$

Then subtract from 30:
$30 - 17 = 13$

First, solve the expression inside the parentheses:
$8 + 5 = 13$

Then subtract from 25:
$25 - 13 = 12$

First, solve the expression inside the parentheses:

$4+3=7$

and

$5-2=3$

Thus, the equation becomes:

$7\times3$

Now, perform the multiplication:

$7 \times 3 = 21$.
