3(z - 4)/(1 - 4)
seems like only on the bottom mathematically, then we see
3(z - 4)/- 3
= - (z - 4)
=======
Without parentheses, the expression is way too ambiguous.
1/3
5 1/3
Yes, 1/3
2-(-1)= 2+1= 3 When a parenthesis is preceded by a minus sign, remove the parentheses and the minus sign before the parentheses and change the sign of each term within the parentheses. When a parenthesis (-1) is preceded by a minus sign, -(-1) remove the parentheses ( ) and the - sign before the parentheses and change the sign of each term -1 within the parentheses +1
1/5
Yes, it becomes 1 over 3.
6/2 = 3/1 = 3
2
2.625 is, regardless of where your parentheses were.
Yes, 3/12 reduces to 1/4.
No. Assuming no parentheses, a/b/c = (a/b)/c = a/bc. For example, 1/2/3 = (1/2)/3 = 1/6. If there are parentheses for the last 2 terms, such as a/(b/c), then it is ac/b. Similarly, if you see it written out as a complex fraction with the a on the top half and the b/c in the bottom half, then it is the same as ac/b.
