The Wolfram|Alpha math team adds new and exciting content to Wolfram|Alpha on a daily basis! In fact, over the past few months we’ve added a wide range of features and we will be introducing them in a blog series here. Lately, we’ve made an effort to make Wolfram|Alpha a powerful learning tool for those learning arithmetic! If you are either teaching or learning addition, multiplication, or basic math word problems, Wolfram|Alpha can help you.
Let’s start with addition! We will start easy, 4+7.
As you can see, users can follow the number line to see that 4 + 7 is 11, or they can count the Manipulatives in the pod below.
The number line is especially useful when you are adding negative numbers.
You can even add (or subtract) three or more numbers. Let’s check it out:
Of course, Wolfram|Alpha can also help with adding and subtracting fractions. How about 3/4 + 2/3?
In this case, you can use the pie charts to help visualize what this problem really means. You can also use the Step-by-step button to see the steps to adding these fractions.
Don’t worry, if you are already learning multiplication, we’ve also added some visuals for you!
Let’s start with 5*3.
In the Illustration pod, you can see that a 5 by 3 rectangle contains 15 boxes. Of course you can do this with bigger numbers as well.
You might not want to sit there and count the boxes, but I promise, there are 100 little squares in a 10 by 10 square. Of course, in this example, you also have the ability to see the steps for multiplication of 10*10.
And if you have mastered simple arithmetic and are working toward word problems, we have support for simple word problems as well. Let’s check out the following example: Bob has 11 apples. He gives 3 to Sarah. How many apples does Bob have now?
Once you have become a pro at arithmetic and word problems, don’t worry, Wolfram|Alpha’s math support goes FAR beyond this. Be sure to continue exploring Wolfram|Alpha for all of your math help!
