+
+ORIGINAL:
+var i;
+if ((n - Math.floor(n)) >= .5) {
+  i = Math.ceil(n);
+} else {
+  i = Math.floor(n);
+}
+
+//Math.ceil returns the smallest integer greater than or equal to the given number.  eg. 2.4 = 3;
+//Math.floor returns the smalelst integer less than or equal to the given number.  eg. 2.4 = 2;
+//for my own purposes, setting var i =6;
+// ORIGINAL WITH WORKING NUMBERS:
+// var i;
+// var n = 3.2;
+// if((3.2- 3))>= .5 {
+// 	i = 4;
+// }
+// else {
+// 	i = 3;
+// }
+
+//In other words, we are rounding up.  
+2a. ANSWER:
+var i;
+i = Math.round(n);
+
+2b.  
+
+ORIGINAL:
+var y, Banana = (x? false : true);//Does x evaluate to true?  then answer will be false.
+if (Banana) // value of x is false 
+  y = false
+else // if xIsFalse value is false:
+  y = x
+
+//This is so many double negatives... I replaced "xIsFalse" with Banana in my tests.  
+//Ternary operator:  points to remember, if the value on the left of the ? is TRUE, then the value in the  middle is chosen.  
+//if it is FALSE, the value on the right is chosen.  
+// Also of note is that the value of xIsFalse will change depending on what the value of x is.
+
+2b. Option 1:
+//It seems that if x is true, y is also true and if x is false, y is also false.
+var y, x;
+y = x;
+
+2b. Option 2:
+//write it in ternary expression...I wasn't sure if y'all wanted it to stay as a ternary operator.
+y = (x? y=false: y=x)
+
+ORIGINAL:
+2c.  
+for (var count = 15 - i; count < 15; count = count + 1) {
+	i = i-1;
+	console.log(i+1)//this doesn't alter the for loop--it's a result.
+}
+
