Systems and Magnitude part 5

4. - numbers expressed as the product of a base-10 number and a number between 1 and 10. (2.56 x 10 = 25.6; 4.32 x 10-4 = 0.000432)
8. - two numbers are relatively prime if they share no common factors. (34 and 15)
10. - the process of writing a number in terms of its prime factors. (12=2×2×3)
11. - numbers that have a specific value. (-2, 3, 1/2, 3.2, √2)
12. - A number is simplified to its closest multiple of 10, 100, 1,000, etc.( 26 rounds to 30)

1. - a prime number or term that can be multiplied by another to get a number. (2 × 6 = 12, 2 is a prime factor)
2. - a fraction composed of 1 over any rational number; the inverse of a whole number. (1/2 or 1/19)
3. - infinite set of natural numbers and zero. (0,1,2,3, ...)
5. - dividing the numerator and denominator by any common factors to put the fraction in lowest terms. (2/4 = ½ )
6. - symbol used to indicate a root. √121 = 11
7. Product Property - When a real number is multiplied by 0, the result is 0. (5 × 0 = 0)
9. - natural numbers greater than 1 that have no numbers that will divide into them without a remainder. (2, 3, 5, 7....)
11. - A comparison that shows the relative size of two or more values. (The ratio of boys to girls is: 4 to 5; 4:5; 4/5; 0.8.)
