Description: ► My Pre-Algebra course: kristakingmath.com/prealgebra-course Pick a number between 20 and 100 (that means not 20 or 100, but anything between them ;D ). Add the digits of your number together. Subtract that amount from your original number. Add the digits of your new number together. Guess what? You get 9 every time, no matter which number you originally choose! Try it out on any number you want, and you’ll see what I mean. #mathtricks Music by Epidemic Sound (epidemicsound.com) ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // kristakingmath.com ● ● ● CONNECT WITH KRISTA ● ● ● Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;) Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!” So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
