BlakeOh, dude, we're talking about some sneaky numbers here. So, basically, we're looking for two numbers that when multiplied give you -4 and when added up, they equal 4. The numbers we're looking for are 2 and -2. They play this cool game where one's positive and the other's negative, but together they make things work out. It's like a math bromance, you know?
Well, isn't that a happy little math problem we have here! To find two numbers that multiply to -4 and add up to 4, we can think of the numbers as factors. The numbers are 2 and -2 because 2 * -2 = -4 and 2 + (-2) = 4. Just remember, mistakes are just happy accidents waiting to be fixed!

How is a negative integer less then any positive integer?
Because positive numbers are to the right of negative numbers on the number line. If you have two numbers, one the negative of the other, and you add the positive to the negative, you get zero. If you add the positive to zero, you get a positive number. So positive numbers are an increase from zero, which is an increase from negative numbers. A negative number may have a greater absolute value than a positive number, but it will always be less than a positive number.
