I did it, but in a weird way.Does it mean i donot fully understand the previous lesson?

Here's my code. alert("Let's do some math!"); var nub1 = prompt("type an random number"); var nub1convert = parseFloat(nub1); var nub2 = prompt("type another random number"); var nub2convert = parseFloat(nub2);

var message1 = "<h1>Math with the numbers " + nub1convert + " and " + nub2convert + " </h1>"; var message = nub1convert + " + " + nub2convert + " = " + (nub1convert + nub2convert); var message3 = nub1convert + " * " + nub2convert + " = " + (nub1convert * nub2convert); var message4 = nub1convert + " / " + nub2convert + " = " + (nub1convert / nub2convert); var message5 = nub1convert + " - " + nub2convert + " = " + (nub1convert - nub2convert); document.write(message1); document.write('<br/>'); document.write(message); document.write('<br/>'); document.write(message3); document.write('<br/>'); document.write(message4); document.write('<br/>'); document.write(message5);

What would you say is the "weird" part of this code?

Other than longer variable names and the use of individual variables and output statements for each line, it looks much like the instructor's example. While the other method is a bit more compact, your code should perform identically.

Getting the right result is most of the point of a program, so good job. :+1: Refinements like efficiency will come with practice.

Oh, and when posting code, use the instructions for code formatting in the Markdown Cheatsheet pop-up below the "Add an Answer" area. :arrow_heading_down:   Or watch this video on code formatting.

Thank you for your answer . Taking this course is the first time i try to learn programing. I would feel uncertain if my answer do not match the teacher's. thanks!

Your code will often not match exactly. Since the teacher focuses on illustrating specific lesson points, your own code might sometimes even be more efficient and compact!
