What happens when multiplying by positive and negative numbers?
When multiplying by two positive numbers for example 5x8 = 40 it will end in a positive. If you had one negative number and one positive its will always end in a negative no matter what for example 7x-3 = -21. That's a maths fact same with multiplying two positives you will always end with a positive number.
What are indices?
Indices are the little numbers shown above but next to a number or letter for example "24"
in this case the 4 within the two numbers is the indices, an indices can also look like the one above but instead the number "2" would be replaced with a letter like "x" and so on.
When multiplying numbers that have indices involved the one rule to follow is if the indices number is even then the final result will be positive when the indices is odd it will mean the final result would be negative. This rule never changes and will always be used when dealing with indices and having to multiply them together.
