Question

20-(-2)^2/(7-9)*13

Answer 1

This is what you wrote.
Is this what you mean with the 20 to the left not in the fraction?
What about the 13? Is it in the denominator, or does it just multiply the fraction?

\( 20 -\dfrac{(-2)^2}{(7 - 9)} \times 13 \)

Answer 2

\[20-(-2)^2\div(7-9)*13\]

Answer 3

Ok, let's start.

Answer 4

What is \( (-2)^2 =\) ?

Answer 5

Parenthesis with an exponent

Answer 6

xD

Answer 7

I mean

Answer 8

4

Answer 9

Right. Notice the number being squared is -2. \( (-2)^2 = (-2) \times (-2) \)
What is that equal to?

Answer 10

Ok, you got it.
Also what is 7 - 9 = ?

Answer 11

-2

Answer 12

Great. Now we can include that in our next step.

\( 20-\color{red}{(-2)^2}\div \color{green}{(7-9)}*13\)

\( = 20- \color{red}{4} \div \color{green}{(-2)} *13 \)

I used colors to clarify we have done so far.

Ok, so far?

Answer 13

Yes

Answer 14

All we have left to do is a subtraction, a division, and a multiplication.
Now we do multiplications and divisions in they order they appear from left to right.

Answer 15

so -4/-2?

Answer 16

Correct.

Answer 17

No, wait. The minus sign is the subtraction. Do just 4 / (-2)

Answer 18

\( = 20- \color{red}{4} \div \color{green}{(-2)} *13 \)

\( = 20- \color{red}{4 \div (-2)} *13 \)

\( = 20- \color{red}{(-2)} *13 \)

Answer 19

Now we do the multiplication.

\( = 20- \color{red}{(-2) *13} \)

\( = 20- \color{red}{(-26)} \)

Now we do the subtraction.

\(= 20 + 26\)

\(= 46\)
