nice trick here
if you don't have a pencil or pen or notebook near you ,you can multiply in ur brain
ok we start
take one number wit 2 digits example 25
and multiplying with 45 how?
the last digit of 45 multiply with 25 (5x25) equals 125 add the zero to the number 1250 and substract with number 125 (without zero) (1250-125) equals 1125.
Multiply 25*45 in ur note book to verify if is ok the result is 1125
ok thnx all bye

hi there I'm using Visual Studio 2005(visual Basic)
I'll tell you  some codes

sqrt of number

math.sqrt("number")

we can insert one textbox with name txtnum
and in code to write this

dim n as integer
n = val(txtnum.text)
msgbox(math.sqrt(n))

Adding number
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a+b)

Subtracting Numbers
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a-b)

Subtracting Numbers
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a-b)

Multiplying Numbers
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a*b)

Dividing Numbers
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a/b)

Squaring Numbers
insert to textboxes 1.txtnum1 , 2. txtnum2

dim a,b as integer
a = val(txtnum1.text)
b = val(txtnum2.text)
msgbox(a^b)
