First, we place the multiplication exercise in parentheses:
We solve the exercise in parentheses:
Now we obtain the exercise:
We reduce the addition exercise:
Now we obtain the exercise:
The question mark is the unknown, therefore we will refer to the exercise as an equation.
We arrange the exercise to isolate the question mark:
We reduce:
We move 47 to the other side and change to the correct sign:
We divide both sides by -1 to change to the correct sign:
\( \frac{6}{3}\times1=\text{ ?} \)
Mathematics has a specific order of operations (PEMDAS)! Multiplication and division must be done before addition and subtraction, regardless of position in the equation.
Remember PEMDAS: Parentheses, Exponents, Multiplication/Division (left to right), Addition/Subtraction (left to right). In this problem, comes first!
That's totally possible! Don't worry if your answer is negative. Just make sure you follow the order of operations correctly and check your work by substituting back.
While you could guess and check, using algebraic steps is more reliable. Treat the ? as a variable, follow order of operations, then isolate it step by step.
Substitute your answer back into the original equation: . If it equals 29, you're right!
