Answer 1

Explicație pas cu pas:

692+543-124-245

1233 - 124 - 245 =

1109 - 245 = 864

897+(259-145)-27=

897 + 114 - 27 =

1011 - 27 = 984

6272-(325+841)-22=

6272 - 1166 - 22 =

5106 - 22 =

5084

6538-1234-1549=

5304 - 1549 =

3755

82+[55-(22-11)]+6=

82 + ( 55 - 11) +6 =

82 + 44 + 6 =

126 + 6 =

132

6923-(591-213)+253=

6923 - 378 + 253 =

6545 + 253 =

6798

{52+[54-(22+11)]+39}-50=

[ 52 + ( 54 - 33) + 39] - 50 =

( 52 + 21 + 39) - 50 =

(73 + 39) - 50 =

112 - 50 =

62

956+[69-(58+22-34)]-8=

956 + [ 69 - ( 80 - 34)] =

956 + ( 69 - 46) =

956 + 23 =

979

22+{51-16+[8-(6-0)]}-1=

22 + [ 35 + ( 8 - 6)] - 1 =

22 + ( 35 + 2) - 1 =

22 + 37 - 1 =

59 - 1 = 58
