This one seems hard, but it's very simple really...

You can easily figure out the day of the week for any date given.  Here's how...
Use this table to help you calculate.
January        0
February       3
March           3
April              6
May              1
June              4
July               6
August          2
September    5
October        0
November     3
December    5


Step1: Pick a date. Ex: 23rd June 1986
Step2: Find the number of the month on the list, June is 4.
Step3: Take the date of the month, that is 23
Step4: Take the last 2 digits of the year, that is 86.
Step5: Find out the number of leap years by dividing the last 2 digits of the year by 4, 86 divide by 4 is 21.
Step6: Now add all 4 numbers: 4 + 23 + 86 + 21 = 134.
Step7: Divide, finding the remainder of your quotient Ex: 134 by 7 = 19 remainder 1.


The reminder tells you the day.
Sunday          0
Monday         1
Tuesday        2
Wednesday   3
Thursday       4
Friday           5
Saturday       6

Here's another very cool math trick...


Step 1
Ask a friend to think of a number between 1 and 10.
Example: 8
Step 2
Get them to double it.
Example: 16
Step 3
Ask them to add 10 to the answer.
Example: 26
Step 4
Then get them to divide by 2.
Example: 13
Step 5
Ask them to tell you what number they now have.
Example: 13
Step 6
You subtract 5 from this and tell them what their original number was.
Example: 13 - 5 = 8
Note: If you wish to take turns to practice your mental maths, you can also use 2 and 3 digit numbers to make it harder!

Add up the following numbers out loud, starting at the top and, adding on each number as you go -

1000
40
1000
10
