Question

{235+(945:7x8)-1000]:5-33}x7=210

Answer 1

{235+[(135x8)-1000]:5-33}x7=210
{235+[1080-1000]:5-33}x7=210
(315:5-33)x7=210
(63-33)x7=210
30x7=210
210=210

Answer 2

{ [235 + (945 : 7 x 8 ) - 1 000] : 5 - 33} x 7 =210 ( Adevarat)
= {[235 +( 135 x 8) - 1 000 ] : 5 - 33 } x 7 =
= [ (235 + 1 080 - 1 000) : 5 - 33 ] × 7 =
= [ ( 1 315 - 1 000 ) : 5 - 33 ] × 7 =
= ( 315 : 5 - 33 ) × 7 =
= ( 63 - 33) × 7 =
= 30 × 7 =
= 210
