How many of these easy sums can you do in one minute? Challenge your friends to see who can get the best score.

Here is a great phone app that will help you with your arithmetic so you don’t need to be afraid when you are faced with that non-calculator exam. It’s called Maths Tricks and shows you lots of short cuts to performing calculations and gives you endless practice to improve your speed and accuracy. Best of all it’s free!

You can find it on Google Play. I am recommending this because it is good, not because I have any connection to the app.

1. Write down your date of birth using 6 figures. So 25th December 1974 would be 25.12.74

2. Write down the last two digits of the year. (eg 74)

3. Divide by 4 and ignore the decimal part or remainder. (eg 74 ÷ 4 = 18)

4. Add together the answers to 1 and 2 (eg 74 + 18 =92)

5. Add the number of the day of your date of birth. (eg 92 + 25 =117)

6. Add a number according to your month of birth as follows.

JAN  1 (0 for Leap Year)   How do you tell if a year is a leap year?

FEB 4  (3 for Leap Year) How do you tell if a year is a leap year?

MARCH 4

APRIL 0

MAY 2

JUNE 5

JULY 0

AUGUST 3

SEPT 6

OCT 1

NOV 4

DEC 6

(eg 117 + 6 for Dec = 123)

For years beginning 18..   add 2

For years beginning 19.. add 0

For years beginning 20.. add 6

(eg 123 +0 = 123)

Divide your answer by 7 and work out the remainder.

(eg 123÷ 7 = 17 remainder 4)

The remainder gives the day of the week you were born on.

1 = Sunday

2= Monday

3= Tuesday

4= Wednesday

5= Thursday

6 = Friday

7 = Saturday

(s0 25.12.74 was a Wednesday)

Ask your teacher (or somebody else) to

1.  Write down your house number.

2.  Double it.

3.  Add the number of days in a week.

4.  Multiply by 50.

6. Subtract the number of days in a year. (not a leap year)

The answer is your teachers house number and their age!
