(- 3) multiplied by 2-8 divided by (- 4); (1 / 2-1 / 3) divided by (- 1 / 6) + - 2 times (- 14) -The fourth power of 1 is divided by the second power of (- 5) multiplied by (- 5 / 3) + 0.8-1. [50 - (7 / 9-11 / 12 + 1 / 6) times the second power of (- 6)] divided by the second power of (- 7). (there should be a process)

(-3)*2-8/(-4)
=(-6)-(-2)
=(-6)+2
=-4
(1/2-1/3)/[-(1/6)]+(-2)*(-2)*(-14)
=1/6/6/1+(-2)/2/14
=1/36+[-(1/14)]
=1/36+14
=14 1/36

(- 1) multiplied by [- 3's Square multiplied by (- 2 / 3's Square) - 2] divided by (- 2 / 3)

If you copy the title correctly and the brackets are correct,
=51

(1-2 of the square) times (1-3 of the square) times (1-4 of the square) times (1-5 of the square) =?
The square difference formula of mathematical synchronization

=(1+1/2)(1-1/2)(1+1/3)(1-1/3)……………… (1+1/5)(1-1/5)
=3/2*1/2*4/3*2/3…… 6/5*4/5
=(3/2*4/3*5/4*6/5)(1/2*2/3*3/4*4/5)
=6/2*1/5
=3/5
