![]() Head, but you could do trial and error and think about it. It go into 1000? It goes into it eight times. And I say how many times doesġ00 go into 100- how many times does 125 go into 100? None. The right, I need to move this one over two to the right. Probably added too many- if I move this decimal over two to So we say 1.25 goes into 100.00- I'm going to add aĬouple of 0's, I don't know how many I'm going to need, Let me make the pen thinĪgain, and go back to the orange color, OK. There, you can I guess rewatch the video. What x is and we know how we got to there. Here, just because I used up too much space. Probably don't know what a hedge fund is. To 100, so x would equal 100 divided by 1.25. I actually work at a hedgeįund, and I'm doing this type of math in my Sit and think about it a little bit, maybe rewatch the video,Īnd hopefully it'll, over time, start to make a lot Number grows by 25%, and it becomes 100, that means thatġ.25 times that number is equal to 100. Problems, you're going to intuitively say, oh, if some And what's 1 plus 0.25? That's easy, it's 1.25. The distributive property in reverse- equals 100. Just the same thing as 1 plus 0.25, plus x- we're just doing x is the same thingĪs 1x, right? So 1x plus 0.25x, well that's Level- actually this might be level 3 system, level 3 linearĮquation- but the bottom line, we can just add theĬoefficients on the x. X plus 0.25 of x is equal to 100, and now actually we have a I start with x and it grows by 25%, so x plus 25% of x isĮqual to 100, and we know this 25% of x we can just rewrite as Might have to break out a little bit of algebra. Some amount of money, it grows by 25%, and I end up with How much did I originally have? Notice I'm not saying that Grows 25%, and after growing 25%, I now have $100. Let's say I start off with someĪmount of money, and after a year, let's says my portfolio So if I start off with $95.00Īnd my portfolio grows- or the amount of money I have- growsīy 15%, I'll end up with $109.25. ![]() This for you to read, especially this 2 here. Plus 15% of 95, which is the same thing as 95 plus 14.25, And so it turns out that IĪctually made an addition error, and the answer is 14.25. Than 15, so I knew my answer of 15.25 was wrong. That 15% of 100 is 15, so if 15% of 100 is 15, how canġ5% of 95 be more than 15? I think that might Interesting question? How did I know thatġ5.25 was a mistake? Well, I did a reality check. And we bring the 0 here, it'sĩ5, 1 times 5, 1 times 9, then we add 5 plus 0 is 5,ħ plus 5 is 12- oh. Actually, is that right? I think I made a mistake here. 5 times 5 is 25, 9 times 5 isĤ5 plus 2 is 47, 1 times 95 is 95, bring down the 5,ġ2, carry the 1, 15. I think I'm about to run out of space- 95 times 0.15. Another way to say it, the 95ĭollars has grown by 15%. Times, it's a little higher than a decimal- So 95 plusĠ.15 times 95 is what we have now, right? Because we started with 95ĭollars, and then we made another 15% times what So we know we write 15% as aĭecimal, as 0.15, so 95 plus 0.15 of 95, so this is Investor, that 95 dollars is going to grow by 15%. Going to grow just because I was an excellent stock 95 dollars, right? And I'm going to earn, or I'm So I'm starting with $95.00,Īnd I'll get rid of the dollar sign. ![]() I think you might be able toįigure this out on your own, but of course we'll do someĮxample problems, just in case it's a little confusing. This year in my stock portfolio with $95.00.
