Division by zero is undefined.
12 divided by 4 plus 2 times 3 = 9
3+2+3²-1 = 5+8-1=12
Since there are no brackets, evaluating it gives 187.89Also, your spelling and grammar are dreadful. It is plus, not pluss. The correct form is times, not time's which is the possessive form and means belonging to the 12 (or 48).
2/3 divided by 4/9 plus 1/2 2/3 times 9/4 = 18/12 + 6/12 = 24/12 = 2
24/-2 + 7 = -12 + 7 = -5

24 + 4 = 28
15-3=12 2+4=3 12*3=36 So the answer is 36...I hope I'm right!
10+2÷(4x3)= 10+2÷ (12)= 12÷(12)= 1
