## Solving One-Step Equations (Negative and Positive Solutions)

Directions: Use the digits 1 to 9, at most one time each, to create two equations: one where x has a positive value and one where x has a negative value. Source: Robert Kaplinsky

## Multi-Step Equations – Positive (or Negative) Solution

Directions: Using the digits 1 to 9, at most one time each, create an equation where x has a positive (or negative) value. Source: Daniel Luevanos

## Sine Functions

Directions: Use the digits 1 to 9, at most one time each, to fill in the boxes and make two true number sentences. Source: Robert Kaplinsky

## Complex Number Products

Directions: Use the integers -9 to 9 at most one time each, place an integer in each box to make a positive real number product and then repeat the process to make a negative real number product. You may use all the integers each time. Source: Robert Kaplinsky

## Equilateral Triangle

Directions: Using the digits 1 to 9, at most one time each, fill in the boxes to fill in the circles of the triangle. The sum of the numbers on each side of the triangle is equal to the length of that side. Arrange the numbers so that the triangle is an equilateral triangle. Source: Erick Lee
