\(\left(-67\right)+125+\left(-33\right)+75\)
\(=\left[\left(-67\right)+\left(-33\right)\right]+\left(125+75\right)\)
\(=100+200=300\)
_______
\(86.\left(-108\right)+86.9-86\)
\(=86.\left[\left(-108\right)+9-1\right]\)
\(=86.\left(-100\right)=-8600\)
_______
\(23.\left(-16\right)-23.84+300\)
\(=23.\left[\left(-16\right)-84\right]+300\)
\(=23.\left(-100\right)+300\)
\(=-2300+300\)
\(=-2000\)
______
\(235-5\left[\left(5^3-3^3\right):14\right]\)
\(=235-5\left[\left(125-27\right):14\right]\)
\(=235-5\left[98:14\right]\)
\(=235-5.7\)
\(=235-35\)
\(=200\)
_______
\(95-\left(129-74\right):5+2022^0\)
\(=95-55:5+1\)

\(2022\cdot99+2022=2022\left(99+1\right)=2022\cdot100=202200\)
\(135\cdot3^3+5\left(3^3\cdot4-3^4\right)\)
\(=135\cdot3^3+5\cdot3^3\cdot4-5\cdot3^4\)
\(=3^3\cdot\left(135+5\cdot4-5\cdot3\right)=3^3\cdot140=1260\)
95 - (129 - 74) : 5 + 2022⁰
= 95 - 55 : 5 + 1
= 95 - 11 + 1
= 95 - 10
= 85
-------
(-67) + 125 + (-33) + 75
= (125 + 75) - (67 + 33)
= 200 - 100
= 100
--------
86.(-108) + 86.9 - 86
= 86.(-108 + 9 - 1)
= 86.(-100)
= 8600
