Using ALL four and ONLY
the four digits 1, 9, 9, and 7 each time, form expressions for all the numbers
from 1 to 100. You may use
+, -, x, ÷, and ( ).
If you find an expression that works, bring it to school and put it up on our class poster. Be sure to initial your work so you get credit! Have fun!
