 // YOUR CODE HERE
+### `maxOrMin(num1, num2, max)`
+
+Define a function `maxOrMin` that takes three parameters: two numbers and a boolean.  Have it return the larger of the two numbers if the boolean is true, otherwise have it return the lesser of the numbers.
+
+ffunction maxOrMin(x,y,z){
+ if ( z == true){
+     console.log("its true!");
+   if ( x < y){
+     return y;
+   } else return x;
+
+ }
+ console.log("it's false");
+}
+maxOrMin(6,4,true);
+
+
+
+
+### `sillySum(arr)`
+// YOUR CODE HERE
+var myArray=[1,4,5];
+var multi = 0;
+
+
+for (var i = 0; myArray.length > i; i++){
+
+   multi += (myArray[i] * i); // I made syntax error here. because of () I spent hours! I better learn from it :)
+}
+
+console.log(multi);
+
+
+### `numSquare(max)`
+
+Create a function called `numSquare` that will return an array of all perfect square numbers up to, but not exceeding a max number.
+
+var myArray=[1,2,3,4];
+var squareArray=[];
+var square;
+function numSquare(y){
+  for (var i=0; i < myArray.length; i++){ // SYNTAX ERRORS!
+   if ( y < myArray[i]) {
+    square = myArray[i] * myArray[i];
+    squareArray.push(square);
+    console.log(square);
+    }
+    else console.log("number is bigger");
+}
+console.log(squareArray);
+
+}
+numSquare(3);
+
+### `isPrime(num)`
+
+Create a function that returns true if the number passed in is a prime number and false if not.
+
+function isPrime(num){
+  if (num % num ===0){
+    return true;
+
+  } else
+  return false;
+}
+
+### `primes(max)`
+
+Using your `isPrime` function, create a function primes that will return an array of all prime numbers up to, but not exceeding a max number.
+
+// working on it
+var ilter = [1,2,3,4];
+var ilter2 = [];
+var ilter3=[];
+//for (i = 0; i < ilter.length; i++){}
+
+ilter.forEach(function isPrime(element){
+  if (element % element === 0){
+ilter2.push(element);
+
+
+}
+else ilter3.push(element);
+
+
+
+  });
+console.log(ilter2);
+console.log(ilter3);
