Logic Level 1

$\large 18 \ \square \ 12 \ \square \ 4 \ \square \ 5 = 59$

Replace each $\square$ with one of $+,-,\times,\div$ to make the equation true.

Submit your answer as a 3 digit number, where:

$1$ represents $+$
$2$ represents $-$
$3$ represents $\times$
$4$ represents $\div$

Example : If your answer is $+, -, \times$ then enter the answer as $123$ .

The answer is 341.

X, ÷,+ makes it true. Hence, 341 is the solution. 18X12÷4+5. Guys this was an easy question. This is my first solution since I joined brilliant. Please upvote!!!

Thanks for ans

PEMDAS makes the answer wrong so this question is poorly written

No try GEMS

Using PEMDAS it does work. 18*12=216 216/4=54 54&5=59

132 would make it work as well but for some reason it claims it's wrong. 18+12x4-5=59 follow bedmas. 12x4=48 48-5=43 43+18=59

$43 + 18 \not = 59,\text{ but 61.}$

That's what I had. Told me it was wrong. I call bull.

59 is a prime number, so that we know there will be addition/substraction somewhere. Also, 59 is odd number. The only odd number available is 5, so it must be + or - before 5.

So far we have to get 54 or 64 from those 3 numbers. We know we need × to get that high. Then, the rest is quite obvious

× ÷ +

Great, I went by the same logic to :)

$\large 18 \ × \ 12 \ ÷ \ 4 \ + \ 5 = 59$

There is one solution and I plugged in the numbers and got the right answer which is 341

18×12÷4+5=59 This is the answer

Something that can be made out is as $59$ is an integer, therefore division is only possible between 12 and 4. Again adding or subtracting 5 can only return a odd number. So, X is left. This is just getting the idea.

Moderator note:

I disagree that "the only way to get an integer is to divide by 4". For example, we could have $18 \div 12 \times 4 + 5$ to obtain an integer.

I meant to say it is only possible with respect to the answer.(You know this question is just a hit and trial.)

Numbers 4 and 5 can't be factored to equal any number with the digit 9. So I thought of using those for add or subtract. This decision wasn't final. I new the 18 and 12 can be sued factored all that together but divide. At first I added to see how big a number I or low I got nope didn't work. I kept experimenting until I got a reasonable number like 216 from multiplying. I thought I wonder what dividing by 4 might get me. I did that then boom got it. This might not always work but somehow it worked for me.

It's such an easy question.ryt. ...using bodmas rule. ..v can solve it 18×12÷4+5

Once you mutiply the first 2 numbers, i.e. 18 and 12, you get 216. From then it is easy to notice that by dividing the number with 5 you would approach the 50s levels and once you actually do it you will see it makes complete sense as you only need to add 5 to the result to reach the final number, i.e. 59.

The answer is 341.
