This is stupid.

I can do this in my head, why should I bother to use these things!

- Show me a rectangle of 3 square units. Double this area.
- Show me a rectangle of 3 square units. Square this area.
- Show me a rectangle of 3 square units. Take the opposite of this area.
- Show me a rectangle of - 3 square units. Take the opposite of this area.

Write the code and the algebraic expression or equation or statement for each.

- three
- three, different from the first answer
- zero
- zero in another way
- a number
- three less than a number
- double the value of three less than a number
- the opposite of three less than a number
- the opposite of the sum of a number and two
- the product of 3 and the sum of 4 and a number
- double the sum of a number and five
- four less than the sum of a number and six
- an integer
- an odd integer
- the next odd integer after the odd integer in #18
- the sum of two consecutive odd integers
- The sum of two consecutive odd integers is eight.
- The sum of three consecutive odd integers is one more than triple the middle integer.

22b. The sum of three consecutive odd integers is triple the middle integer. - double the value of three less than a number (See #11.)

- Add 4 and 1.
- Add -3 and 2.
- Add -3 and -4.
- Add (2x + 4) and ( -x + 2).
- Subtract 2 from 4 by "add the opposite."
- Subtract 2 from 4 by "take away."
- Subtract 4 from 2 by "add the opposite."
- Subtract 4 from 2 by "take away."
- Subtract (2x + 4) from ( -x + 2) by "add the opposite."
- Subtract (2x + 4) from ( -x + 2) by "take away."
- Multiply 3 and a number.
- Multiply 3 and a the opposite of a number.
- Multiply - 3 and a the opposite of a number.
- Multiply 4 and the sum of a number and three
- Multiply (x + 1) (x + 3).
- Multiply (x + 1) (x - 3)
- Divide x
^{2}+ 2x - 3 by x + 3 - Divide x
^{2}+ 2x - 4 by x + 3 - Solve: One more than a number is the same as double the number.
- Solve: 2x + 4 = x - 1
- Solve: -x = 2
- Solve: x + 1 = 2x
- Solve: Double the sum of a number and one is equal to five less than double the number.
- Solve: Double the sum of a number and one is greater than six.
- Solve: The sum of two consecutive odd integers is eight.
