Verified Answer :

d= (12)/(3)(4)
d = 12/12
d = 1

D = (12) / (3)(4). Substitute the values of a, b, and c into the equation.
D = 4 (4) : Use DMAS from left to right. Remember that DMAS means "from left to right, division and multiplication and then addition and subtraction," rather than "from left to right, division, then multiplication, then addition, then* subtraction." It's an important difference.
D = 16
