Select the correct combination of mathematical signs to replace the * signs and to balance the following equation.
6 * 4 * 12 * 12
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → ×, -, =
Each option is put in place of the * signs in order, and the equation must balance.
Option (1): \(6+4-12=12\) gives \(-2=12\), which is false.
Option (2): \(6+4-12+12\) has no equals sign, so it is not an equation.
Option (3): \(6=4-12+12\) gives \(6=4\), which is false.
Option (4): \(6\times4-12=12\) gives \(24-12=12\), which is true.
