The Outwood Grange Family of Schools 2016 Teacher Notes 1.Students are given roughly 10 numbers each week and, using only the digits 2,0,1,6, are asked to use any mathematical operation to create the given numbers. 2.Students will need to be aware of BIDMAS, this is an agreed 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 × 3= 4 + 6= 10
