 Understand the operations of addition, subtraction, multiplication and division as they apply to positive and negative numbers. Add and subtract positive and negative numbers. Write a number in each circle so that the number in each square equals the sum of the two numbers on either side of it. Multiply positive and negative numbers. Write a number in each circle so that the number in each square equals the product of the two numbers on either side of it. Complete this multiplication table. Positive and negative numbers are used. E3: Multiplication table 1 E4: Multiplication table 2 more difficult E5: Missing numbers: Answer questions such as -12 + = -19 Complete the magic squares E6: 3 x 3 magic square E7: 4 x 4 magic square

 Understand that multiplying does not always make a number larger and that division does not always make a number smaller. E8: Multiply by 10, 100 or 1000 eg 0.6 x = 60 E9: Divide by 10, 100 or 1000. E10: Multiply and divide by 0.1 and 0.01 eg 0.6 x = 0.06 E11: Just multiply E12: Just divide E13: Multiply and divide by an integer power of 10 eg 6.6 x = 0.0066 E14: Just multiply E15: Just divide

 Understand that addition is the inverse of subtraction, and multiplication is the inverse of division. I think of a number, add 3.7, then multiply by 5. The answer is 22.5. What is the number? E16: Using whole numbers E17: Using numbers to one decimal place A function machine changes the number n to the number 3n + 1. What does it do to these numbers? 2, 5, 9, 21, 0 What numbers must be input to get these numbers? 10, 37, 100 E18: Function machine

 Order of operations Click to reveal the answers E19: Mixed operations eg Find the value of 3 + 6 x 5 + 2. Put in brackets to make the value 45, ie 3 + 6 x (5 + 2) = 45 Use these buttons to generate one problem or a set of 10 problems.
