Introduction to PHP
Basic Math Operations
Numbers
You already know how to use the echo function to output text. But what about numbers and mathematical calculations?
You can also use echo to display these. When you want to output the result of a mathematical expression, there's no need to use quotes (" " or ' '). Simply write the expression directly inside echo, and it will be evaluated and displayed on the screen.
main
If you print a number and a string to the console, they will look the same, which is something they have in common. However, there are things we can do with numbers that we can't do with strings, and vice versa. For instance, we can apply mathematical operations to numbers.
Math Operations
Almost no program can do without mathematical calculations, so PHP supports the following mathematical operations:
The code below performs basic arithmetic operations on different numbers and outputs the results to the screen.
Output the result of adding 5 and 3:
main
Output the result of subtracting 7 from 10:
main
Output the result of dividing 15 by 3:
main
Output the result of multiplying 4 by 6:
main
Output the remainder of dividing 17 by 5:
main
