• so 7907 is lessthanthe ader number
• jackie, you are correct, 7907 is less than 7970.
One way to show that something is "less than" something else (in mathematics) is to use the "`<`" symbol. So, as Sal explains at , when you use the "`<`" symbol you are saying that the number on the left of the symbol is "less than" the number on the right. This means that you would write the comparison as:
`7907 < 7970`
• What is the difference between natural numbers and whole numbers? My 3rd Grade teacher only uses the word "natural numbers" but the title says " Comparing whole number place values" .
• How about negative numbers ? Is -1 a whole number ?
• e Eyes.
• 1+1000
1000+1
What is the value of +
• what if you change the number of 7 to 7 hundred or 70 to 7 hundred
• I have a question um do i have to multiply or add or subtract
• No you don’t substract or add
• The answer is 7907 < 7970. This is because "7970" is a larger number than "7907".
• every negitive number is a whole number.

• Negative numbers are not considered whole numbers, just the counting numbers 0, 1, 2, … If you want to include the negatives of the counting numbers, you have to say they are integers. There are also negative numbers which are not integers such as -1.5.
