<p>What is the easiest way to solve this question?</p>
<p>guess and check</p>
<p>Is it the one about the cards 1-7? If so all you got to do is pay attention to the working and you would be get</p>
<p>Add all the cards together, and you get 28. The easiest way to get a units digit of 7 is to remove the 1 card and get 27. Doesn’t really take any guess & check.</p>
<p>To remove the 1 card is not only the easiest but also the only way to get a number with units digit of seven.</p>
<p>This is a really easy question 
Add then remove</p>
<p>The explanation is on the website…</p>
<p>^I was thinking the exact same thing.</p>
<p>When there is a distinct and obvious way to check your answer, there is no excuse for anyone to miss a question like this. And yet…1 out of 2 people missed this. Jesus people are dumb.</p>
<p>the wording was a bit odd, i stared at it for a minute or two trying to figure out what the heck it was trying to say ( i thought it meant adding up to 8) but then i figured it out. lol</p>
<p>Yeah the wording messed me up on the question</p>
<p>Ahh… i didn’t realize add and subtract… fail</p>
<p>Lol I did mine at 2am when it first went out and I was dead tired. So I thought it was asking what one card to pull out for the TOTAL sum to be 7 lol</p>
