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);
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
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; //PUT BEFORE CONSOLE.LOG!!! console.log(“Initial Count:”, count); // Output: 10 // Increment using ++ count++;
%%js
//problem 1
let a = 4
let b = 156
console.log("Sum of a and b:")
console.log(a+b)
console.log("Difference of a and b:")
console.log(a-b)
console.log("Product of a and b:")
console.log(a*b)
console.log("Quotient of a and be:")
console.log(a/b)

%%js
//problem 2
let numDivident = 238
let numDivisor = 6
let expression = numDivident % numDivisor
console.log("The remainder when",numDivident,"is divided by", numDivisor,"is",expression)

%%js
//problem 3
let count = 17 // Btw I didn't know if each time we should work with the latest value of the variable or the original one.
console.log("The original value is:",count)
count++;
console.log("This is the value + 1:",count)
count--;
console.log("this is the value -1:",count)
count+=13;
console.log("This is the value +13:", count)
count-=13;
console.log("This is the value -13:", count)
