That depends on what exactly you want to 'do' with it.
If you want to write it in a way that will attract some attention,
a peacock-blue felt-tip marker could work well for you.
If you want to solve it for 'x', you could do it like this:
-9x - 3 = 60
Add 3 to each side:
-9x = 63
Multiply each side by -1 :
9x = -63
Divide each side by 9:
x = -7
cos60= 1/2 sin60=1.732/2
60 x 60 = 3,600
60 is the square root you are looking for. 60 x 60 = 3600.
x = 10
60 - 20 = 20 + 20=============
54 + -90x
This is non-linear
7 + ( 9 x ( 3 - 1 ) ) = 25
9x3 is also 9+9+9. 9x3 = 27
27
60 equals seconds in a minute
To find the sum of something means to add. Example: 9X3=27 The sum of 9x3 is 27.
60
600 divided by 60 equals 10.
60 = 60/1.
9x6=54! P.S. Here is a trick, hold uot both of you're hands and if you want to know 9x3, put down your third finger and anything in front of that finger is then tens and the ones behind it are the ones so using the trick 9x3=7 (ONLY WORKS FOR NINE!)
20 times 3 equals 60
