49 : 7 + [ 49 x ( 48 : 3 + 36 : 9 + 7 : 7 )] : 10 =
7 + [ 49 x ( 16 + 4 + 1 )] : 10 =
7 + ( 49 x 21 ) : 10 =
7 + 1029 : 10 =
7 + 102 , 9 = 109 , 9

49:7+[49+(48:3+36:9+7:7)]:10= 49:7+[49+(16+36:9+7:7)]:10= 49:7+[49+(16+4+7:7)]:10= 49:7+[49+(16+4+1)]:10= 49:7+[49+(20+1)]:10= 49:7+[49+21]:10 49:7+ 70:10= 7+7=14
