Use the digits in the year 2010 and the operations
+, -, x, ÷, sqrt (square root),
^ (raise to a power), and ! (factorial),
along with grouping symbols, to write
expressions for the counting numbers 1 through 100.
- All four digits must be used in the expression.
- Only the digits 2, 0, 1, 0 may be used.
- Multi-digit numbers such as 20, 210, or .02 MAY
be used this year.
- The square function may NOT be used.
- The integer function may NOT be used.
- Students should be introduced to the fact that 0! by definition
is equal to 1. See Dr. Math's answer to Why
does 0
factorial equal 1? for more information.
-
Dr. Math also tells us that, depending on the context where
0^0 occurs, it can be 1, indeterminate, or undefined/nonexistent.
For this game we will accept the value 0^0=1.
See the Dr. Math FAQ
0 to
the 0 power for more information.
- This site is intended for the posting of answers generated by
students. Teachers may submit answers for their students.
- Each answer should include the expression, the name of the
student, the student's grade level, and the name of the school.
- Use the Web form once for each answer you would like to contribute.
If you send more than one solution per form submission, we will be
unable to include your answers on our solution page.
The four digits can be used in any order, but we will be more likely to publish expressions with the digits in the order 2, 0, 1, 0.
