- 3. addition and multiplication of numbers you can change the order of the numbers in the problem and it will not affect the answer a+b=b+a or axb=bxa
- 6. any real number that cannot be expressed as the quotient of two integers √2, √3, √5, √11, √21
- 10. the positive integers 1,3,7,84
- 11. represents equal parts of a whole or collection 1/2
- 12. the smallest positive interger that is evenly divsable by both a+b. lcm(a,b)= |axb|/gcd(a,b)
- 14. involving the condition that a group of qualities connected by operators gives the same result (axb)xc=ax(bxc)
- 18. a relationship between two quantities, normally expressed as the quotient of one divided by the other 2:5
- 20. the largest factor that all the numbers share 18-(2,3) 24-(2,3)
Down
- 1. a number without fractions; an integer 5,15,7,20
- 2. multiplying the sum of two or more addends by a number this will give the same result as multiplying each addends individually by the number and then adding the products together a(b+c)=ab+ac
- 4. the distance from zero that a number is on the number line without considering direction.Never a negative|ax+b|=c
- 5. a way of expressing a number as a product of its prime factor 48=2x2x2x2x3
- 7. a number that is expressed as the ratio of two integers where the denominator should not equal zero -2 = -2/1, -5 = -5/1, -14 = -14/1
- 8. a whole expressed in hundredths (value/total value)x100%
- 9. an equality that remains true even if you change all the variables that are used in that equality (0)=a and 0+(a)=a
- 13. the likehood of an operation on elements of a set a+b=R
- 15. the equation between two variables that a straight line gives when plotted on a graph 2x-3=0, 2y=8
- 16. a whole number;a number that is not a fraction can be positive, negative, and zero -5, 1, 5, 8, 97
- 17. an equation in which two ratios are set equal to each other a:b::c:d=a/b=c/d
- 19. pairs of mathematical manipulations in which one operation undoes the action of the other f(x)=3x+2
