My students will be handing their sheets next week and I need to come up with the answer key FAST. Hopefully someone can provide me with the answer key. Here are the rules: Write math expressions that equla the numbersfrom 1 to 100 -you may only use the numerals 1,4,8 and 9 -you may only use each numeral ONCE in each expression -you MUST use all 4 numerals in every expression -you may not use 2 digit numbers -you may use any combination of math operations -your *** is to find at least 80 different expressions for values from 1 to 100 -you may use a MAX of 10 duplicate expressions to reach a total of 80 -you may use a calculator and you may ask your family to help
