How the Numbers Add Up
This is primarily for students, but everyone is welcomed to give it a try and leave comments.
It’s pretty easy to do 11 x 1 through to 10 without putting a lot of thought to it, but how can we calculate 11 x 11, or 11 x 12, or 11 x 13 and so on. I came up with an easy way to do it without a calculator. [I have seen many online suggestions, but nothing exactly like this, so give it a try]
|
11 x 11 11 11 121 |
11 x 97 97 97 1067 |
11 x 534 534 534 5874 |
Cool! Right?
Ok, here is the last one.
Investments and Savings Files
Suppose your bank account pays interest monthly with an EAR of 4%.
What interest rate will you earn each month and if your balance
today is $0, how much will you need to save at the end of each month
to accumulate $120,000 in 20 years?
Pull out your calculator or use Excel and give it a try. Good luck!
