lol I need to know this too.
Every aspect of mathematics depends upon integers, and even if you don't do any mathematics, you count things with integers. If you even want to know how many guests you are having for dinner, you need to use integers.
Oh, dude, let me break it down for you. If you multiply three integers, the product will be positive if all three integers are either positive or negative. If you have two negative integers and one positive integer, the product will be negative. So, like, it depends on the mix of positives and negatives, you know?
We have three integers, and we know they are all sequential integers, so we can refer to them as: x, x + 1, x + 2 We are also told: 3(x + 2) = x + (x + 1) + 47 Now we can use that relationship to solve for x: 3x + 2 = 2x + 48 x = 46 So our numbers are 46, 47 and 48
What you need to know about integers is that integers is the name for the group of numbers that include whole numbers and negative numbers. But integers DO NOT include fractions.
