# 10 Basic Computations You can Do with Wolfram Alpha

In the **previous post**, I have shared to you the advantages of using Wolfram Alpha. In this post, I am going to list some of the basic calculations that can be done using the same app. Note that you can use these commands both in the iOS version or the web version.

1. Do Basic Arithmetic with Integers, Fractions, and Decimals

150 + 32

1200 – 3

15.8 * 2.5

15/5

1/5*(3 – 8)

2. Compute Decimal Approximation to a Specified Number of Digits

pi to 1000 digits

e to 50 digits

3. Plot Graphs

Plot x^3 + 2x^2 – 3x + 1

Plot x^2 + y^2 < 3 and y > x

4. Solve and Equation and Factor Polynomials

x^2 – 4x + 6x – 24 = 0

factor x^2 – 10x + 9

5. Calculate Derivative, Integral, and Solve Ordinary Differential Equations

Integrate sin x dx from x = 0 to pi

Derivative of x^4 sin x

y” + y = 0

6. Compute Properties of Geometric Figure

annulus, inner radius = 2, outer radius = 5

dodecahedron

7. Computes LCM, GCD, Prime Factorization

gcd(60,72)

lcm (12, 15)

factor 850

8. Compute a Truth Table and Generate a Venn Diagram

P && (Q||R)

(complement S) intersect (A Union B)

9. Identify Formula for a Sequence and Solve a Recurrence Relation

5, 9, 13, 17, 21, …

f(n) = f(n-1) + f(n-2), f(1) = 1, f(2) = 2

10. Compute, Compare, and Convert Measures

12 miles + 10 kilometers

175 lb vs 100kg

10 megabytes to mebibytes
