arithmetic.js

//Make a function that does arithmetic!

// Given two numbers and an arithmetic operator (the name of it, as a string), return the result of the two numbers having that operator used on them.

// a and b will both be positive integers, and a will always be the first number in the operation, and b always the second.

// The four operators are "add", "subtract", "divide", "multiply".

// A few examples:(Input1, Input2, Input3 --> Output)

// 5, 2, "add"      --> 7
// 5, 2, "subtract" --> 3
// 5, 2, "multiply" --> 10
// 5, 2, "divide"   --> 2.5
// Try to do it without using if statements!

function arithmetic(a, b, operator){
    if(operator === "add"){
        return a+b
    }else if (operator === "subtract"){
        return a-b
    }else if(operator === "multiply"){
        return a*b
    }else{
        return a/b
    }
}

console.log(arithmetic(1, 2, "add"))// 3, "'add' should return the two numbers added together!");
console.log(arithmetic(8, 2, "subtract"))// 6, "'subtract' should return a minus b!");
console.log(arithmetic(5, 2, "multiply"))// 10, "'multiply' should return a multiplied by b!");
console.log(arithmetic(8, 2, "divide"))// 4, "'divide' should return a divided by b!");
