Is this equation true? Well, what do we have on the left, seven plus one is eight, Let's say I had seven plus one is equal to three plus four. To one, which we know is not true, so this is notĮqual, this is not equal. This would be the same thing as saying that 10 is equal If I were to write this, is this true? Well, you might be tempted, hey, if I put a one (chuckles) and a zero together, it's gonna look like a 10,īut that's not, this is not how we do mathematics, this And this is also eight, so once again the equal sign is just saying that this, what we have on the left, is the same as what we have on the right. This is another way of writing eight, nine minus three plus two Side I have zero plus one minus one, well, one minus one is zero, so this is all going to be eight. So this, this, if I were to, if I were to compute it, that's equal to eight. See, nine minus three is six, plus two is eight, minus zero is eight. zero plus one minus one plus eight, is this true? Well, let's figure out What if I were to write, what if I were to write nine minus three plus two minus zero is equal to, is equal to. And sometimes you mightĮven see someone do something like this, that means not equal. They swapped, or we swapped (chuckles), the one and the eight, This, is this true? Well, the number on the left here is 18, the number on the left isġ8, the number on the right is a different number, it is 81, it is 81. If I were to write down, I won't even read it out, Let's write some statements using equal signs, someĮquations, you could even say, using equal signs, and figure out which of them are actually true. What's on the left-hand side is the same amount as what's So the equal sign does not mean just give me the answer or just, you know, add the numbers or subtract the numbers.

What is six plus one, well, that's seven.

You could even mixĪddition and subtraction, you could write, you could write that six plus one is the same thing, is equal to, eight minus one. Whatever three plus two is, that's going to be the same thing as whatever two plus three is. Notice, here, we're notįiguring out the answer, we're just saying that You could write that three plus two is equal to two plus three. You could have written, you could have written five And you didn't have to write it this way. Is the same amount, the same quantity, as what What the equal sign is saying is that what's on the left side Two plus three, well, the answer is five. Think that the equal sign just says, hey, give me the answer, figure out what two plus three is. Math, you see things like two plus three is equal to five, or you might see six plus one is equal to seven, or you might see eight minus two is equal to six.
