However, we can still use it to make the calculation easier. In this case the multiplication table above cannot give an immediate answer. It is often necessary to multiply numbers that are bigger than 10. The cost of the trip to the cinema will therefore be £32. How much will the total cost of the trip be? We need to calculate 4 lots of £8, which is written 4 × 8.įind 4 on the vertical red column and 8 on the horizontal red column, the answer is in the cell where the two lines intersect: 32. Megan is taking her three brothers to the cinema, she needs to buy 4 tickets in total and each ticket costs £8. The table above can help us quickly calculate the answer to the following problem. It doesn't matter which way around you search for the numbers if you find 4 in the first column and 6 in the first row you get the same answer, 24.

To obtain the answer to 4 × 6, for example, find 4 on the top (red shaded) line and find 6 on the left hand (red shaded) column – the point where the two lines intersect is the answer: 24. This table gives the answers to all multiplications up to 10 × 10. 4 × 2000 for example is 4 × 2 = 8 with 3 zeros: 8000.įor simple and quick multiplication it is useful to memorise the multiplication or ' times table’ as shown below. When multiplying by 100 we write two zeros at the end, by a thousand we write three zeros at the end and so on.When a whole number is multiplied by 10 we can simply write a 0 at the end (there is one zero in 10 because it is 1 × 10).When a number is multiplied by two we are doubling the number.Any number multiplied by 1 stays the same.Understanding Statistical Distributions.Area, Surface Area and Volume Reference Sheet.Simple Transformations of 2-Dimensional Shapes.Polar, Cylindrical and Spherical Coordinates.Introduction to Cartesian Coordinate Systems.Introduction to Geometry: Points, Lines and Planes.Percentage Change | Increase and Decrease.Mental Arithmetic – Basic Mental Maths Hacks.Ordering Mathematical Operations - BODMAS.Common Mathematical Symbols and Terminology.Special Numbers and Mathematical Concepts.How Good Are Your Numeracy Skills?
