I got a question like this 1/3m=4
I got the answer 12/3=4
but when I checked the answer, it was {12}.
What was the purpose of the curly brackets?

The curly brackets mean "set," like a set of solutions. So {12} means m, the variable in this particular equation, is equal to 12. You are supposed to solve the equation for m. (1/3)m = (1/3)(12) = 4



If you had an equation like x^2 - 7x + 12 = 0, then {3, 4} is the set of solutions. Both numbers work when you substitute them into the equation for x.

MoonRose is wrong.



The answer is 12, not 4.



You divide 4 by 1/3 to get 12.



This still doesn't answer the question. WHAT DO THE SQUIGGLY BRACKETS MEAN?! D:<

there's no common definition, that each and every physique agree on. they might desire to be defined whilst they're used, and in many circumstances are interior the beginning up of a math textbook. in any different case, they may well be used to distinguish which "associating close mark" is linked with which previous "associating open mark".
