How can i make nine equations with the numbers 2, 7 and one other number to equal 8. The first equation should have one as the other number, then two and so on up to 9. I can only use a number once for each expression. I can use arithmetic symbols, decimals, exponents and parentheses. So far, I have equations using the numbers 1, 2, 3, 6 and 9. How can I use 4, 5, 7 and 8. I could really use the help!
