He jumped 3 levels and scored highest in his class." - Kathy J. "We received my son's MCT scores from 10th grade (end of last year).

I now have a 30 composite score and a full ride to the University of Alabama and you guys are 100% responsible!" - Andrew T., Sacramento, CA After studying the problems I missed with Zoom Math's Trace feature as my guide I was able to pull my math section of the ACT up to a 31. "Prior to teaching myself with Zoom Math my ACT on the math section was 24 three times in a row.
"Your programs were instrumental in helping me pass and more importantly, understand, the Algebra and Business/Finance math courses that I had to take to obtain my Associates degree." - Mark C. "This app has saved my life!" - Natalie W. I must say that ZOOM MATH got me through this hard process wonderfully" - Sabrina K. "I am a 43 yr old mom of five sons and going back to college has been a struggle and math is one of my weakest areas. "Prior to using Zoom I had debilitating anxiety over math success, now that fear is completely gone." - Lori B., Los Angeles, CA "What I like is that it allows me to totally grasp the concepts of Algebra like never before." Lori B, - Los Angeles, CA I can catch my errors on the spot." - Lori B., Los Angeles, CA "The Trace function is invaluable because it allows me to relax and check my work. "Where I was spending 20+ hours on homework, Zoom reduced it to under 10." - Lori B. I type these four equations into Zoom Math:Īnd Zoom Math gives me the correct answer $t=39$. For example, if you want to know the 20th term in the sequence 1, 3, 5, …, then $t$ is the answer you’re looking for, $a=1$, $n=20$, and $d=2$. For arithmetic sequences, you can always use the formula $t=a+(n-1)d$, where $t$ is the term you want to calculate, $a$ is the first term of the sequence, $n$ is the number of the term you want to calculate, and $d$ is the difference between consecutive terms. Of course, Zoom Math is good with equations, so if you type in the formula yourself, Zoom Math can solve it for you. For example, if you want to know the 20th term in the sequence $1, 3, 5, …,$ Zoom Math can’t calculate that for you. Zoom Math can’t do much else with arithmetic sequences, at least not directly. To type that problem, type it exactly the way it looks, including the three dots. For example, Zoom Math can calculate the answer to $1+3+5+…+99$. In Zoom Math 200 and above, you can calculate the sum of an arithmetic sequence.
