Solve 1-Step

100

`x/(-4) = 16`

x = -64

200

`1/(9)x=12`

x = 108

300

`2/(7)x = 30`

x = 105

400

`1/(6)x = 1/(3)`

x = 2

500

`4/(3)x = -20/(3)`

x = -5

More 1-Step

100

-4x = 36

x = -9

200

-99x = 0

x = 0

300

-12 + x = 7

x = 19

400

9 + x = 2

x = -7

500

11 + x = -14

x = -25

Simplify Algebraic

Simplify Numeric

100

`2*3^2`

2(9) = 18

200

-3 - 3(-1)

-3 + 3 = 0

300

`2+(-2+6*2)/(5)`

2 + 2 = 4

400

`5+4*(2^3-6)`

5+4(2) = 13

500

`-4-(-2-1)^2-2`

-4 - 9 - 2 = -15

Exponent Rules

100

`(4xy)(-5x^2y^3)`

Multiply; keep; add;

-20x³y⁴

200

`(6h^7)/(3h^2)`

Divide; keep; subtract;

2h⁵

300

`(x^8)/(x^8)`

Same number divided by itself;

= 1

400

Write with positive exponents:

`(x^-2)/(x^2y^0)`

x^-2 goes;

`1/(x^4)`

500

Multiply; keep answer in scientific notation:

`(4.2*10^-12)*(3.1*10^-11)`

Multiply; keep; add; adjust;

1.302 x 10^-22
