"PhotoMath, "the world's first camera calculator" which launched on the App Store earlier this month, has received an update making a number of significant improvements to the application. First, iOS device owners should find that the speed of both math recognition and calculation has been boosted as of PhotoMath 1.1.0. You'll find that using PhotoMath on your iPhone or iPod touch is a more efficient process as of the app's most recent update. Second, PhotoMath 1.1.0 now also allows users to delete their scanning history. If you've been using the application to snap and calculate countless number problems, you'll surely appreciate this change (nobody wants a clogged-up history page in an iOS app, right?)."

Calculator for Windows or Mac - trial or fuill version to download. Also a free online calculator, dashboard widget or google gadget. Advanced calc has a small cost.

"Collecting data on student progress is an important part of making decisions about intervention and how to best support the children in our classrooms.  Running Record Calculator is an app for iOS devices that helps teachers who are administering this type of assessment.  It records students as they read a passage and gives you a quick way to keep track of self-corrections and errors.  After the recording finishes you can enter the word count from the passage to calculate words per minute."

"One snowy January day, I asked a classroom of college students to tell me the first word that came to mind when they thought about mathematics. The top two words were "calculation" and "equation." When I asked a room of professional mathematicians the same question, neither of those words were mentioned; instead, they offered phrases like "critical thinking" and "problem-solving." This is unfortunately common. What professional mathematicians think of as mathematics is entirely different from what the general population thinks of as mathematics. When so many describe mathematics as synonymous with calculation, it's no wonder we hear "I hate math" so often. So I set out to solve this problem in a somewhat unconventional way. I decided to offer a class called "The Mathematics of Knitting" at my institution, Carthage College. In it, I chose to eliminate pencil, paper, calculator (gasp) and textbook from the classroom completely. Instead, we talked, used our hands, drew pictures and played with everything from beach balls to measuring tapes. For homework, we reflected by blogging. And of course, we knit."

"Math 42 is a neat iPad app that I tried earlier this week. The app is one part calculator and one part mathematics tutorial. When students enter an equation into Math 42 they not only receive the answer they also receive a break-down of the steps needed in order to solve the equation. Along with an illustration of the steps students can see alternative approaches to solving a problem."

"There are lots of apps that ca n "wow" a crowd and MyScript Calculator is definitely one of them.  Write an equation (simple or complex) onto your screen and the app will use handwriting recognition software to solve the problem.  This fantastic free app can be used by students to check their work, especially order of operations.  If you've tried this app before update to the most recent version to access all of their great features.  You'll need to try it to believe it!"

"abaCal - Your new online calculator for applied mathematics "

Jet Airways is now capable of accurately calculating and keeping track of aircraft emissions. IBM has more than 50 years experience in aviation. The company uses its software, hardware and services expertise to help top airlines and airports across the globe deliver more highly differentiated customer experiences and improve their operational efficiency. A part of IBMs Integrated Emission Management System, it provides Jet Airways a process to analyse and calculate individual aircraft emissions, which is a complex process involving comparison of flight records and fuel usage data contained in multiple systems ranging from internal aircraft systems to regional navigation data and flight records.

"For too many students, doing mathematics means just plugging numbers into a memorized formula to get an answer. And because they don't understand the formulas they're using, they often fail to use the right one. Take a look at Isaac's work below, for example. He is a fifth grade student who tried to find the surface area of a rectangular prism by incorrectly adapting a previously memorized formula for calculating perimeter. He calculated two times the length plus two times the width (2L + 2W) and tried to account for the height by multiplying it by 4, then adding it to the previous sum. Unfortunately, Isaac is not alone in this type of approach. Students who use formulas by rote may never come to see mathematics as sense-making and may never understand the formulas they use. And there are so many formulas to memorize! Teachers who prematurely introduce students to formulas risk denying them opportunities to develop the necessary conceptual foundations for mathematical understanding."
