Simple Math
To perform arithmetic operations on variables and values C++ supports the following arithmetic operators:
Let’s try:
12345int sum = 10 + 3; // 13 int dif = 10 - 3; // 7 int mul = 10 * 3; // 30 int div = 10 / 3; // 3 int mod = 10 % 3; // 1
By division, any remainder was dropped since we assign the result to the int variable which doesn’t contain any decimals.
You can use all operations above to perform calculations on values, variables, or between variable and value:
123double a = 32 + 13; // 45 double b = a + 25; // 45 + 25 = 70 double c = a + b; // 70 + 45 = 115

Robin has 18$ and Ted has 12$. How much money has each of them in average?
- Calculate the sum of their money and assign it to the variable
sum. - Divide the sum by
2(number of people) to find the average and assign the result to the variableavr. - Print the variable
avr.
Please, don’t forget about semicolon ; at the end of lines.
