These helpers or hints have helped me tremendously. I just love cute little sayings that help me remember English, Spelling and Arithmetic rules.
- The 11 Times Trick – We know the trick when multiplying by ten – add 0 to the end of the number, but 11’s are simple as well when multiplying by double digits.
Take the original number and imagine a space between the two digits (in this example we will use 52:
Now add the two numbers together and put them in the middle:
That is it – you have the answer: 572.
If the numbers in the middle add up to a 2 digit number, just insert the second number and add 1 to the first:
1089 – It works every time.
- To get the first eight digits of pi, count the number of letters in each word of this phrase:
May(3) I(1) have(4) a(1) large(5) container(9) of(2) coffee (6)?
- Divide a number by 3? Just add up all the digits until you have a single number. If THAT number is divisible by three, so is the original number. (I.e. 4545 . If you add 4+5+4+5 you get 18. Then add 1+8, which equals 9. Nine is divisible by three, so you know that 4545 is too.)
- Order of taxonomy in biology:
Kids Prefer Cheese Over Fried Green Spinach (Kingdom, Phylum, Class, Order, Family, Genus, Species)
- Red sky at night, sailor’s delight; (meaning pretty day)
Red sky at morn, sailor’s be warned. (meaning storms)
- MISSISSIPPI – M,i, crooked letter, crooked letter, i, crooked letter, crooked letter, i, hump back, hump back, i.
- A song to learn the order of the presidents of the United States of America.
