# Are There Any Good Ipad Math Apps

What are some good math/science learning apps for iPad for a skilled 7-year old?

I've been very happy with the dragon box games, which cover numbers, algebra and geometry. My 5 year old is largely autonomous with the algebra, even though his arithmetic is not good enough for him to fully appreciate what he's doing (the game makes the rules of algebra very clear, so the game becomes a puzzle). The geometry game required more and-holding to explain where the proof steps come from but he's quite good at them now and as able to prove for me a fresh fact that was not in the game.I've liked their ui approach so much that I've tried to emulate it in our arithmetic lessons, specifically by working with digit cards that are replaced by other cards, instead of forcing him to write things out. For a child with a short attention span, this is easier to follow.

What is the best app for learning maths?

Wolfram alpha, can solve very complex to very basic math problem even advanced math can be done on both PC as well as mobile app, but using them for solving problem at very early age for children will have a great negative as lose their interest to solve them as the software easily does that for them.some other apps are:PCalc Lite (iOS)Digits (iOS) or CalcTape (Android)Tydlig (iOS)MyScript Calculator (Android, iOS)Free Graphing Calculator (iOS) or Algeo Graphing Calculator (Android)Wolfram Alpha (Android, iOS)Mathway (Android, iOS)

MATH App Problem Help!!!?

since "decays continuously at a rate of 5% PER HOUR" is given,
appropriate formula is N = 50*0.95^t

a. N = 50*0.95^25.9 ≈ 13.24 mg <-------

b. 25 = 50*0.95^t, 0.95^t = 0.5 , t = ln 0.5 / ln 0.95 ≈ 13.51 hr <------

note:
------
if the q were simply "decays continuously at a rate of 5%"
we would have used N = 50e^(-0.05t) and got slightly different results.
a. 13.69 mg
b. 13.86 hrs
but to use it here is not correct

----------
use the analogous A = P(1± r)^n to understand the concept
here A = P(1-0.05)^n = P*0.95^n
