Answer 1

a) 168:12 + (2018-1826)*7 = 14 + 192*7 = 14 + 1344 = 1358

b) 32*87+56*32-32*43 = 32 (87 + 56 - 43) = 32 * 100 = 3200

Answer 2

a ) 168 : 12 + ( 2018 - 1826 ) x 7 =  

= 14 + 192 x 7

= 14 + 1344

b ) 32 x 87 + 56 x 32 - 32 x 43 =

= 32( 87 + 56 - 43 )

= 32( 143 - 43 )

= 32 x 100

= 3200
