2018 Teacher Notes Students are given roughly 10 numbers each week and, using only the digits 2,0,1,8, are asked to use any mathematical operation to create the given numbers. Students will need to be aware of the order of operations.So the order you should do your calculations in is: - Brackets - Indices - Division and Multiplication. Start on the left and work them out in the order that you find them. - Addition and Subtraction. When only addition and subtraction are left in the sum work them out in the order you find them, starting from the left of the sum and working towards the right. Example What is 4 + 2 × 3= 4 + 6= 10

Challenge

Your challenge: You can use any mathematical operation and ALL of the numbers 2,0,1 and 8 to create sums with the answers from 1 to 100. Each week you will be given a different set of numbers to complete. Calculators are not allowed!

Examples. 0 1 8 so you could have 2 + 0 + 1 + 8 = 11 2 0 1 8 so you could have 20 + 18 = 38 0 1 8 so you could have 8 x 2 + 10 = 26 2 0 1 8 so you could have 82 + 1 + 0= 65

Multiplication Times Product Lots of x You can use: Addition Sum Plus Add + Subtraction Minus Take away Difference - Division Divide Share ÷ Indices Powers Squared2 Cubed3 Square root √ Factorial ! Not sure what this means, find out!
