The "less than" sign and the "greater than" sign look like a "V" on its side, don't they? To remember which way around the "<" and ">" signs go, just remember: 1. BIG > small 2. small < BIG Greater Than Symbol: BIG > small
Sometimes we know a value is smaller, but may also be equal to! To show this, we add an extra line at the bottom of the "less than" or "greater than" symbol like this:
Because there are things we do not know exactly ... So we have ways of saying what we doknow (which may be useful!)
We saw in that previous example that when we change sides we flipped the symbol as well. Here is another example using "≥" and "≤":
OK, this example may be complicated if you don't know Algebra, but I thought you might like to see it anyway:
