This is level 6: yet more questions similar to those in previous levels. You can earn a trophy if you get at least 9 questions correct and you do this activity online.

 1. What number, being increased by 36, will be equal to ten times itself? Working: 2. Find the number whose double increased by 28 will equal six times the number itself. Working: 3. If John's age be multiplied by 5, and if 24 be added to the product, the sum will be seven times his age. What is his age? Working: 4. A father gave his son four times as many dollars as the son initially had, and his mother gave him \$24, when he found that he had nine times as many dollars as at first. How many dollars did the son have at first? Working: 5. A man had a certain amount of money; he earned three times as much the next week and found £32. If he then had eight times as much as at first, how much did the man initially have? Working: 6. A man, being asked how many sheep he had, said "If you will give me 24 more than six times what I have now, I shall have ten times my present number." How many sheep had he? Working: 7. Divide the number 726 into two parts such that one shall be five times the other. How many will be in the larger part? Working: 8. Consider two numbers differing by 852, one of which is seven times the other. How much is the smaller number? Working: 9. A storekeeper received a certain amount the first month; the second month she received £50 less than three times as much, and the third month twice as much as the second month. In the three months she received £4850. What did she receive in the second month? Working: 10. James is 3 years older than William, and twice James's age is equal to three times William's age. What is the age of James? Working: 11. If I add 12 to a certain number, four times this second number will equal seven times the original number. What is the original number? Working: 12. A man bought 12 pairs of boots and 6 suits of clothes for £168. If a suit of clothes cost £2 less than four times as much as a pair of boots, what was the price of a pair of boots? Working:

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.

"These questions have been adapted from 'A First Book in Algebra' by Wallace Boyden. They all are designed to encourage an algebraic solution by setting up an equation (or alternatively simultaneous equations) and solving it. Some of the questions could be classified under the topic of ratio.
In his introduction Wallace Boyden states 'Algebra is so much like arithmetic that all that you know about addition, subtraction, multiplication, and division, the signs that you have been using and the ways of working out problems, will be very useful to you in this study. There are two things the introduction of which really makes all the difference between arithmetic and algebra. One of these is the use of letters to represent numbers, and you will see in the following exercises that this change makes the solution of problems much easier.'."

"On level 4 of the 'algebra in action' section, question 11 says:
"Divide the number 137 into three parts, such that the second is 3 more than the first, and the third five times the second. What is the third part?"
The answer is 100, but it was marked as being wrong, so I tried again, but with 20 (the second number) and 17 (the first number) and it marked 17 as being correct.

[Transum: Thank you so much for taking the time to highlight this error. You were indeed right and the error has now been corrected. Thank you so much.]"

"Is there a way these algebra in action activities can be made into printable worksheets please.

[Transum: Thanks for your feedback Nick. Most of the Transum online exercises can be printed directly from your browser. The input boxes transform into dotted lines for pupils to write their answers on and if the page is being printed by a Transum subscriber, the answers appear at the bottom of the worksheet.]"

Curriculum Reference

See the National Curriculum page for links to related online activities and resources.

Back in 1895 Mr Boyden wrote 'Algebra is so much like arithmetic that all that you know about addition, subtraction, multiplication, and division, the signs that you have been using and the ways of working out problems, will be very useful to you in this study. There are two things the introduction of which really makes all the difference between arithmetic and algebra. One of these is the use of letters to represent numbers, and you will see in the following exercises that this change makes the solution of problems much easier'.

Example for level 6

What number added to twice itself and 40 more will make a sum equal to eight times the number?

Let $$x$$ be the number
$$x + 2x + 40 = 8x$$
$$3x + 40 = 8x$$
$$40 = 5x$$
$$8 = x$$
The number is 8.
