Answer Key for JS Loops Lab

Please note that this key only reflects one of many possible solutions for the "JS Loopy Math" lab. If your output meets the criteria for each exercise, you are on the right track!

for(let i = 0; i <= 100; i++) {
  console.log(i)
}

let sum = 0

for(let i = 0; i <=100; i++){
    sum += i
}

console.log("your total is " +sum)

The sum of all numbers from 0 to 100 = 5,050

for(let i = 0; i < 100; i++){
    n = Math.pow(i,2)
    if(n <= 100){
        console.log(n)
    }  
}

for(let i = 0; i < 100; i++){
    n = i % 2
    if(n === 0){
        console.log(i)
    }  
}

for(let i = 0; i <= 1007; i++){
    if(i % 10 == 7){
        console.log(i)
    }  
}

for(let i = 0; i <= 100; i++){
    if(i % 3 == 0){
        console.log(i)
    }  
}

Challenge 1.

let days = 0
for (let i = 0; i <= 30; i++){
    days += 1
    if (days <= 30){
        let grain = Math.pow(2,i) 
        console.log("On day "+days+" you will have "+grain+" grain(s) of rice.")  
    }         
} 

Challenge 2:

for(let i = 0; i <= 100; i++){
    if(i % 2 == 0){
        console.log("These are the multiples of 2: " + i)
    }  
}

for(let i = 0; i <= 100; i++){  
   if(i % 3 == 0){
        console.log("These are the multiples of 3: " + i)
    } 
}

for(let i = 0; i <= 100; i++){
    if(i % 2 == 0 && i % 3 == 0){
        console.log("These are the multiples of 2 & 3: " + i)
    } 
}

Challenge 3:

for(let i = 0; i <= 100; i++){
    if(i % 2 == 0 || i % 3 == 0){
        console.log("These are the multiples of 2 OR 3: " + i)
    } 
}
