value: 70,000 Example: 6 place: millions value:
6,000,000 Example: 9 place: hundreds
value: 900 digit: number expanded form: to show a number as the sum of the value of this digits Example: 7,965 in expanded form is 7,000+900+60+5 standard form: the usual way of writing a number Example: 234,908 Example: 400+20+2 in
standard form is 422 Example: Fifteen in
standard form is 15 word form: to show a number as
word(s) Example: 14,009 in
word form is fourteen thousand, nine Example: 23.19 in word
form is twenty-three and nineteen hundredths Example: 2.9 in word
form is two and nine tenths Operations sum: answer to an
addition problem addend + addend = sum addend: numbers that are
added together difference: answer to a
subtraction problem product: answer to a
multiplication problem factor factor: numbers that are
multiplied quotient: answer to a
division problem dividend dividend: a number to be
divided Example: 45 divisor: the number by which a dividend is divided Example: 45 Rounding Rounding to the nearest ten. 23 20 75 80 449 450 39 40

and divide 61÷2= 891÷32= 60÷2=30 900÷30=30 Properties of
Multiplication commutative property of
multiplication:
the order of the factors does not change a product. Example: 2 8 = 8 associative property of
multiplication:
the way factors are grouped does not change the product. Example: (2 6 24 = 24 multiplicative identity property: any number multiplied by one remains the same number. Example: 5 distributive property of
multiplication: multiplying a sum by a number is the same
as multiplying each addend by the number and then adding the problem. Example:
2 2 14 = 14 Example:
432 x 4 = (400 x 4) + (30 x 4) + (2 x 4) 1,728 = 1,600 + 120 + 8 1,728 = 1,728 zero
property of multiplication: any
number multiplied by zero will result in the product of zero Example:
