• 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`
• Who else thought this was really ez • 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" .  • Can math get harder than: place value when multiplying and dividing by 10. • Yes, math can get harder than this. There’s multi-digit multiplication (by numbers other than just 10), multi-digit division (by numbers other than just 10), operations with fractions, operations with decimals, percents, conversion between fractions & decimals & percents, exponents & roots, operations with signed numbers (positives and negatives), pre-algebra, algebra 1 & 2, geometry (which could have proofs), trigonometry, probability & statistics, pre-calculus, calculus, and much more! There is always something new and interesting to learn in math.

Have a blessed, wonderful day!
• every negitive number is a whole number. • hello whats up yo
