decimal arithmetic (KristaKingMath)

YouTube Excerpt: ► My Pre-Algebra course: https://www.kristakingmath.com/prealgebra-course In this video we learn how to do decimal arithmetic. We'll look at addition, subtraction, multiplication and division with decimal numbers. Decimal addition and subtraction requires us to line up the decimals vertically and then add or subtract. Decimal multiplication lets us right-align the numbers, multiply like normal, and then move the decimal point over based on the number of digits to the right of the decimal points. Decimal division lets us move the decimal up from the dividend into the quotient. If there's a decimal in the divisor, we have to move it all the way to the right, and move the decimal in the dividend a corresponding number of digits to the right. ● ● ● GET EXTRA HELP ● ● ● If you could use some extra help with your math class, then check out Krista’s website // http://www.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.
