Hi, there.
You have a great site. Thanks a lot. I was wondering if you could tell me where I can get some info. on how to solve the following problem. I was given the answer but I don't know how it is solved.
4+2x(6x2)5=23
Respectfully,
Dorothy
Hi Dorothy,
When evaluating a mathematical expression start inside the parentheses, next do any divisions and multiplications and finally any additions and subtractions.
4 + 2x(6x2)  5  first inside the parentheses  6x2 
4 + 2x12  5  next the multiplication  2x12 
4 + 24  5  now the addition  4 + 24 
28  5  and finally the subtraction  28  5 
23  
Thus 4 + 2x(6x2)5 = 23
Cheers, Penny
