Question

20*{[(4*32+3*4):10]:2+48:8)]}=

Answer 1

20*{[(128+12)/10]/2+6]}=20*{[140/10]/2+6]]=20*{7+6}=20*13=260

Answer 2

$20\times\Big\{\big[(4\times32+3\times4):10]:2+48:8\Big\}= \\ = 20\times\Big\{\big[(128+12):10\big]:2 + 6\Big\} = 20\times\Big[(140:10):2+6\Big] = \\ =20\times\big(14:2+6\big) = 20\times\big(7+6\big) = 20\times 13 = 260$
