Welcome back to code chef. Imagine
buying three chocolates for 10 rupees
each. How does Java calculate the total
cost? Or what if you need to divide
candies among friends? That's where
arithmetic operators come in. They help
Java do all kinds of math for you. Think
of arithmetic operators like tools in a
kitchen. A knife to cut vegetables, a
spoon to mix ingredients, a scale to
weigh flour. Each tool has a specific
job. Just like each operator has a
specific mathematical task, adding,
subtracting, multiplying, dividing, and
finding remainders. In Java, arithmetic
operators are symbols that perform basic
mathematical operations on numbers. The
main operators are plus for addition,
minus for subtraction, asterisk for
multiplication, slash for division, and
percent for modulus, which gives the
remainder. Here's a simple example.
Suppose we have two numbers 10 and
three. We can add them to get 13,
subtract to get 7, multiply to get 30,
divide to get three, and use modulus to
get one, which is the remainder. Each
operation is stored in a variable and
when we print them, Java outputs 13, 7,
30, 3, and 1.
A few quick tips. Division with integers
gives only the whole number part.
Modulus is great for finding remainders,
such as checking whether a number is
even or odd. You can also combine
operators and expressions, but remember,
Java follows operator precedence. So
multiplication and division happen
before addition and subtraction. Now
it's your turn. Try the beginner

calculator.
Read two numbers, perform all arithmetic
operations, and print the results. Today
you learned that arithmetic operators
let Java add, subtract, multiply,
divide, and find remainders. They're
essential for all mathematical
calculations in your programs. Keep
practicing, keep coding and remember
code, debug, repeat, build mastery with
