How do we type the mathematical symbols through key board?

Question

How do we enter mathematical symbols such as square root, cube root using key board? How to type subscripts and superscripts? How to type special symbols like integration, summation?

Answer 1

If you are doing these things on Microsoft word you can use the equation editor.
Click on INSERT
Click on OBJECT
Scroll Down to Microsoft Equation 3.0

You can type all the symbols, greek letters, etc.

Answer 2

If you have Windows XP. Start. All Programs. Accessories. System Tools. Character Map.

Make sure the font is on a normal font like Times New Roman or Arial. Then scroll to the bottom of the window and voila!

Answer 3

other than using Character Map

square root = sqrt
cube root = cbrt
Exponent = x^n, whereas n is the exponent

If you are talking about Logarithms for the subscripts, i just use.
log(base y)x or log(y)x

As for the others, you can you Character Map

² for square
³ for cube
½ for sqrt
Σ for summation, which is found under Windows : Greek using the character map
θ for theta
π for pi, but i juse use pi

Answer 4

depends on the software, otherwise here ae some text representations:

sqrt = square root
^ = symbol for an exponent, ie x^2 is x squared
int = integral
sum = summation

Answer 5

use the ANSI character set. Do this by holding down while typing in a number. try it with a normal number and with a number preceded by 0.

= ²
= ý

Practice it a bit. Look up websites on ANSI.
