• If a number is greater than the next number you will use this symbol >.
• If a number is less than the next number you use this symbol
• If a number is the same as the next number you use the equal sign.

Is 84 greater than, less than, or = to 92?

• Is 84 greater than less than or = to 92?
• First you want to look at the tens place in both, two-digit numbers.
• 8 is in the tens place in 84.
• 9 is in the tens place in 92.
• 8 is less than 9 so 84 is
• As you notice the symbol looks like a mouth. The mouth always eats the greater number, so it is eating 92.

Is 72 greater than,less than, or = to 71?

• As we learned before you want to look at the tens place first to see if 72 is >,
• 7 is in the tens place in 72.
• 7 is also in the tens place in 71.
• Since the tens digit is the same, now you want to look in the ones place.

Is 72 greater than,less than, or = to 71?

• There is a 2 in the ones place in 72.
• There is a 1 in the ones place in 71.
• Since 2 is greater than 1, that means that 72 > 71.
• As you notice the symbol looks like a mouth. The mouth always eats the greater number, so it is eating 72.

Is 64 greater than,less than or equal to 64.

• When you look at the two numbers, you notice that the tens digit and the ones digit is the same in 64.
• When both numbers are the same, that means the two numbers are equal.
• So 64 = 64.
