(-9) / 3 = -3 . Minus nine divided by three is equal to minus three
2a+5
4 times 2 minus 3 divided by 3 is equal to 8 minus 3 divided by 3 which is equal to 5 divided by 3 which gives you 1 and 2 thirds.
The multiplicative inverse of a number a is a number b such that axb=1 If we look at (3-4i)/(5+2i), we see that we can multiply that by its reciprocal and the product is one. So (5+2i)/(3-4i) is the multiplicative inverse of (3-4i)/(5+2i)
(3+2i)-(3+2i)
It is 3 minus 2i
(-2 + 3i) + (-1 - 2i) = -2 + 3i - 1 - 2i = -2 - 1 + 3i - 2i = -3 + i

-3
(-9) / 3 = -3 . Minus nine divided by three is equal to minus three
minus a minus is plus, so it's -8 + 3, which is 3 - 8, or -5

4 times 2 minus 3 divided by 3 is equal to 8 minus 3 divided by 3 which is equal to 5 divided by 3 which gives you 1 and 2 thirds.
