The value to be determined must be on the top line.

The value to be found must be on its own on one side of the equals sign.

Any value moved over the equals sign moves from bottom to top or top to bottom.

The value to be determined must always be on the bottom line.

The value to be determined must be on the top line.

Any value moved over the equals sign moves from bottom to top or top to bottom.

The value to be found must be on its own on one side of the equals sign.

The value to be determined must always be negative.

A = ρl/R

A = R/ρl

A = ρl × R

A = R/ρ

c = a + b - d

c = a + b + d

c = d - a - b

c = a - b + d

c = a + b - d

c = a - b + d

c = a + b + d

c = d - a - b

Convert the action to the opposite on the other side of the equals sign

Keep the action the same on both sides

Only move constants, not variables

Ignore the sign when moving terms

b = √(h² - a²)

b = h² + a²

b = h + a

b = √(a² - h²)
