Why am I learning this?

Mathematicians are not the people who find Maths easy; they are the people who enjoy how mystifying, puzzling and hard it is. Are you a mathematician?

Go Maths

Learning and understanding Mathematics, at every level, requires learner engagement. Mathematics is not a spectator sport. Sometimes traditional teaching fails to actively involve students. One way to address the problem is through the use of interactive activities and this web site provides many of those. The Go Maths page is an alphabetical list of free activities designed for students in Secondary/High school.

"In the decimal number system the value of a digit depends on its position in the number. Each position has a value ten times the position to its right. This is unlike other number systems such as Roman numerals. It is this place value that makes arithmetic easier to perform. Make sure you know the position of the digits that represent thousands, hundreds, tens, units, tenths, hundredths and thousandths at least."

In the decimal number system the value of a digit depends on its position in the number. Each position has a value ten times the position to its right. This is unlike other number systems such as Roman numerals. It is this place value that makes arithmetic easier to perform. Make sure you know the position of the digits that represent thousands, hundreds, tens, units, tenths, hundredths and thousandths at least.

Here is an interactive Place Value Chart to help with you calculations.

Examples

60 x 70 = 6 x 10 x 7 x 10 = 42 x 100 = 4200

20000 ÷ 500 = 20 x 1000 ÷ 5 ÷ 100 = 4 x 10 = 40

Or 20000 ÷ 500 = 200 ÷ 5 = 40
