# How do you subtract (2+3i)-(7+6i)?

$- 5 - 3 i$

#### Explanation:

Taking

$\left(2 + 3 i\right) - \left(7 + 6 i\right)$

we can first distribute the subtraction/negative sign:

$2 + 3 i - 7 - 6 i$

and now combine like terms:

$- 5 - 3 i$

$- 3 i - 5$

#### Explanation:

You have to remember when you are doing this equation, $i$ is a variable just like $x$

When you are adding like terms, you have to group all of them together. Don't forget that you have to remove negative or subtraction signs when you are doing this. You have to bring the negative for all of the terms inside the braket

your equation will then look this,
$2 + 3 i - 7 - 6 i$

Group all of your like terms and your equation will look like this
$3 i - 6 i + 2 - 7$

Now do simple subractions
$- 3 i - 5$

In order to reflect on the equation, we see that the numbers on the first equation are smaller then the numbers in the second bracket. This show that if we were to subtract them, you will get a negative number... just like we got.
