Answers:
1.) A number squared is equal to onethousand nine-hundred thirty-six.
n2 = 1936
2.) A number decreased by twenty is
equal to zero.
n – 20 = 0
3. The product of a number and eight
squared is equal to eighty-eight.
n · 82 = 88
4. A number cubed is equal to 64.
n3 = 64

6. Eight more than a number is 22.
8 + n = 22
7. The product of minus twelve and a
number is twenty-six.
-12 x n = 26
8. The sum of minus twelve and a number
is equal to twenty-two.
-12 + n = 22
