Multiplying any teen (11-19) by 20

Here is a quick trick to multiply a teen (11-19) by 20. Add 10 to the teen, and then multiply by 10. So if you have 14 times 20, that’s 240. Then multiply the ones part of the teen by 10 and add that, so in this case 4 times 10 is 40 + 240 is 280.

Let’s try a hard one: 17 times 20? That’s 270 + 70 = 340. That’s especially easy because 70 + 70 is 140. How about 18 times 20? Well, that’s 280 + 80. 80 + 80 is 160, add in our 200 and you get 360.

You give it a shot.

Math Notes – Project: From zero to hero.

As I’ve mentioned before, I am a 6th grade dropout, not only that but I was “homeschooled” for most of my elementary school years, so my math abilities are pretty non-existent. To correct this problem, I have started studying mathematics; from zero. Here is where I will put my notes.

Behold the power of 0

Something that was pointed out by Scott Flansburg: 0 is a number. No really – it’s not nothing – it’s something. Programmers, often, start counting at zero, but you’d be amazed how your mind changes when you get rid of 10, and start counting at 0. Don’t count: 1,2,3,4,5,6,7,8,9 and 10! Instead, start at 0 and count like this: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9.

Once you do that, you notice that counting is circular!

0 0 0 0 0 0 0 0 0 0 1 1 1
0 1 2 3 4 5 6 7 8 9 0 1 2
