191-28 +3 x 4 x 2-4 x 4+2x5 x3=191-28+12×2-16+10=191-28+24-16+10=163+8+10=181

4x 2x4-2 x4-3 x3 +5x 4 x2 +218=8×4-8-9+20×2=32-8-9+40=24-9+40=15+40=55

(90-81+1) x4 + (2 +6-4)x x4 +5 x 3 x2=(9+1)×4+(8-4)×4+15=10×4+4×4+15=40+16+15=56+15=71

9x 3+9 x4 +9x 2-8x4-3 x 4-2 x 5=27+36+18-32-12-10=63+18-32-12-10=81-32-12-10=49-12-10=37-10=27

200-( 87-81 ) x 4 +7x4-3 x 3 x3 =200-6×4+28-9×3=200-24+28-27=176+28-27=204-27=177
