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

-4x = 36

x = -9

200

-99x = 0

x = 0

300

-12 + x = 7

x = 19

400

9 + x = 2

x = -7

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

-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
