Answer :
From the equations, choice a 4,10,20,30 is the correct one.
How do you solve the equations in order?
In both mathematics and computer programming, the order of operations refers to a set of guidelines on which operations to do first in order to evaluate a certain mathematical expression. The order of operations is a rule that outlines the proper steps to take when analyzing a mathematical equation. We can recall the PEMDAS steps in the following order: parentheses, exponents, multiplication and division (from Left to right), addition, and subtraction (from left to right). The term BODMAS is used in the UK (Brackets, Orders, Divide, Multiply, Add, Subtract). BDMAS is a term used in Canada (Brackets, Exponents, Divide, Multiply, Add, Subtract).
The equation ((4x+12)2)-6 leads to the result 2x, demonstrating that the answer is in multiples of 2.
