8+(14+6) FIND EASIER EXPLAIN WHY
alexandr1967 [171]

Hi there and welcome to Brainly!


The answer to 8+(14+6) = 28. The reason for this is you add what is in parenthesis first then you add the number outside of the parenthesis. This follows the PEMDAS rule which is called the order of operations. PEMDAS is an acronym which stands for Parenthesis, Exponents, Multiplication/Division, and Addition/Subtraction, this is the order you should follow when solving any problem.
