Описание к видео Shortcuts to Multiplying Decimals

CC: by ME!!
Guess what! I have 2 other ways you can use to solve a multiplying decimals problem, and they are BOTH quicker than doing a standard algorithm multiplication and taking care of your decimal point at the end!!
Use when multiplying a decimal and a whole number.
You can't use them all the time, but when you know what to look for, and you can see it in your question, you can nail it in a few seconds.
This is really neat. Watch all the way through the first AND second examples to see all the possible alternatives to your shortcut approach.
Let me know which shortcut YOU like best.
