# What can this rebus solve? How can this rebus be solved?

This is my first rebus, constructive suggestions are welcome. Enjoy! Mistake: the diagonal of the green circle on the right should be from the top right to the bottom left instead of from the top left to the bottom right. Sorry!

Top full view of the blue-white thing in green background:

something similar to this

Hint:

1:

the only piece of knowledge needed from one of the tags is given in the rebus

2:

is here, but things are basic here ■ ‿ ■

3: OK, gonna ruin the tag:

it should be

4: top left

A name I call myself

5: top middle

$$CN(terra)$$

• If it doesn't give away the answer, what's in the second picture? Can't really tell, is it a bar of soap? Commented Jan 26, 2019 at 10:47
• @J.Dionisio sorry but which do you mean by second pic? thanks! Commented Jan 26, 2019 at 10:50
• the one with something blue with what appears to be grass in the background Commented Jan 26, 2019 at 10:50

• @OmegaKrypton I liked this puzzle a lot, however, why do you start it with 'sol', when you actually mean 'mi'? 'Mi' would be a line lower. Commented Feb 8, 2019 at 11:32

We know the final solution is:

Like so:

First two pictures

As hinted, the musical note (a 'G' in the treble clef) relates to "a name I call myself" which itself relates to the third note in the Solfège system, 'mi' (see Do-Re-Mi from The Sound of Music). The second image is part of a "frisbee", which would give us the 'is b' we need as the first term in the formula.

So with "mi" + (n) + "is" (sounds like us) + "b", we get "minus b" or $$-b$$

Third picture

Credit to @Matthew Barber, who discovered that "The Chinese for Saturn is 土星, the first part of which looks a bit like the ± sign.", which gives us our $$±$$ symbol

Fourth picture

The rotation symbol gives us "rot", and the inner symbol looks like a zero, which gives us a second 'O' to make "root", or $$√$$
The first icon inside the circle is a 'B' chord for a guitar, but "squared", which gives us the $$b^2$$
The second icon inside the circle is 4 air-conditioners (credit to @Hugh for spotting that). Commonly abbreviated to 'AC', this would give us $$4ac$$
Together with the minus symbol in the picture, we get $$√b^2 - 4ac$$, also known as the 'discriminant'

Bottom picture

This is 2 A's, but because they are "under" all the other pictures, we could say that the top row is "over $$2a$$", giving us the bottom of the formula

• There is a "minus" followed by four air conditioners in the top-right image, that's "minus four ACs" or $-4ac$. Commented Feb 4, 2019 at 22:28
• @Hugh nice observation! :D Commented Feb 4, 2019 at 22:30
• ...and I'll bet that the other thing in the green symbol is the "b squared" part (dot in a square --> b squared?). Commented Feb 4, 2019 at 22:35
• In addition, the fact that the frisbee is "cut off" intrigues me. This is enforced by the fact that Omega Krypton uses the words "full view" to describe the frisbee in the spoiler. Commented Feb 4, 2019 at 22:38
• The partial frisbee could be rot13[vforr = vf o]?

One part of the puzzle, which I don't think has been mentioned yet:

The Chinese for Saturn is 土星, the first part of which looks a bit like the ± sign.

• correct, nice job! Commented Feb 7, 2019 at 5:40
