Variables: Multiplication and Division
Most of us have learned these facts many times. Use this quick drill to refresh your mind—knock off the dust.
- x times y =x times y = xy
- x(y) =x(y) = xy
- x * y =x * y = xy
- x · y =x · y = xy
- 2x(y) =2x(y) = 2xy
- 2x(3y) =2x(3y) = 6xy
- 4x(3y) =4x(3y) = 12xy
- 3x(6y) =3x(6y) = 18xy
- x times x =x times x = x^{2}
- x(x) =x(x) = x^{2}
- x(xy) =x(xy) = x^{2}y
- xy(y) =xy(y) = xy^{2}
- x ÷ y =x ÷ y = ^{x}/_{y}
- y ÷ x =y ÷ x = ^{y}/_{x}
- x ÷ 2 =x ÷ 2 = ^{x}/_{2}
- 2 ÷ x =2 ÷ x = ^{2}/_{x}
- x ÷ 3 =x ÷ 3 = ^{x}/_{3}
- 3 ÷ x =3 ÷ x = ^{3}/_{x}
- 3x ÷ y =3x ÷ y = ^{3x}/_{y}
- 3x ÷ 2y =3x ÷ 2y = ^{3x}/_{2y}
- 6x ÷ 4y =6x ÷ 4y = ^{3x}/_{2y}
- 4x ÷ 4y =4x ÷ 4y = ^{x}/_{y}
- 6x ÷ 3y =6x ÷ 3y = ^{2x}/_{y}
- 4x ÷ 2y =4x ÷ 2y = ^{2x}/_{y}
