Multiplication In the first 6 matches of the season, a football team scores 4 goals each time. If you know your multiplication tables, this is an easy calculation. Otherwise, you can work it out using addition. How many goals do they score altogether? 4 x 6 is the same as 6 + 6 + 6 + 6. Adding: 6 + 6 + 6 + 6 = 24 6 x 4 = 24 To do any calculations like this, it helps if you know your multiplication tables – or if you can use a multiplication square. To multiply two numbers, choose one number from the top row and another from the left-hand column. Follow the first number down and the second one across. Their product is where the two numbers meet. 1 2 3 4 5 6 7 8 9 10 2 4 6 8 10 12 14 16 18 20 3 6 9 12 15 18 21 24 27 30 4 8 12 16 20 24 28 32 36 40 5 10 15 20 25 30 35 40 45 50 6 12 18 24 30 36 42 48 54 60 7 14 21 28 35 42 49 56 63 70 8 16 24 32 40 48 56 64 72 80 9 18 27 36 45 54 63 72 81 90 10 20 30 40 50 60 70 80 90 100 Notice that 6 x 4 = 4 x 6 Num3 Page 1 of 2 N1/E2.5 Multiplication Brush up your tables by completing this multiplication square. 1 2 3 4 5 6 7 8 9 10 2 3 4 5 6 7 8 9 10 Copy the multiplication square or cut this one out and stick it on some card.
