For the equation to be true, it should be 24 ÷ 6・9 – (5^2 + 8) = 3.
"Grouping Symbols" are Parentheses "( )" and Brackets "[ ]". The most commonly used symbol is the parenthesis.
Now, to show that the equation is true, you must solve by following PEMDAS (Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
1. Solve the parentheses.
5² or 5 x 5 is 25.
25 + 8 = 33.
The equation now says 24 ÷ 6 x 9 - 33 = 3
2. Solve all multiplication and/or division from left to right.
24 ÷ 6 = 4
4 x 9 = 36.
The equation now says 36 - 33 = 3.
3. Solve all addition and/or subtraction from left to right.
36 - 33 = 3.
3 = 3, thus meaning that the equation is true.
I hope this helps!
