Javascript Mathematical Operations
Homework
Problem 1: Basic Arithmetic
Define two variables, a
and b
, with values of your choice. Compute the following operations and log each result to the console:
- Sum of
a
andb
- Difference of
a
andb
- Product of
a
andb
- Quotient of
a
divided byb
Console.log code
console.log(“Sum:”, a + b);
console.log(“Difference:”, a - b);
console.log(“Product:”, a * b);
console.log(“Quotient:”, a / b);
%%js
let a = 1;
let b = 2;
console.log("Sum:", a + b);
console.log("Difference:", a - b);
console.log("Product:", a - b);
console.log("Quotient:", a / b);

Problem 2: Modulus Operator
Define two numbers, num1
and num2
. Use the modulus operator %
to find the remainder when num1
is divided by num2
. Log the result to the console.
Instructions:
- Define a variable
num1
(the dividend). - Define a variable
num2
(the divisor). - Use the modulus operator
num1 % num2
to calculate the remainder. - Log the result to the console using
console.log()
.
console.log code
console.log(“Remainder:”, YOURVARIABLE (CORRECT MATHEMATICAL OPERATION) YOUROTHERVARIABLE); // Output: 1
%%js
let num1 = 7;
let num2 = 2;
console.log("Remainder:", num1 % num2); // Ouput: 1

Problem 3: Increment and Decrement
Define a variable count
and set it to an initial value. Increment and then decrement the variable in two different ways:
- Using the
++
and--
operators. - Using the
+=
and-=
operators. Log the result after each operation.Instructions:
- Define a variable
count
and assign it an initial value (e.g., 10). - Use
++
to increment the variable by 1 and log the result. - Use
--
to decrement the variable by 1 and log the result. - Use
+=
to increment the variable by a specific value and log the result. - Use
-=
to decrement the variable by a specific value and log the result. - Log result 3 times (Use these operations to increment/decremnt your number atleast 3 times)
Example:
```javascript let count = 10; console.log(“Initial Count:”, count); // Output: 10 // Increment using ++ count++;
%%js
// initial value
let count = 10;
// Increment by 1
count++;
console.log("After incrementing by 1:", count);
// Decrement by 1
count--;
console.log("After decrementing by 1:", count);
// Increment by 10
count += 10;
console.log("After incrementing by 10:", count);
// Decrement by 5
count -= 5;
console.log("After decrementing by 5:", count);
