I got a question like this 1/3m4I got the answer 12/34but when I checked the answer, it was {12}.What was the purpose of the curly brackets?
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.
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:
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.
