    a) 12 + 3. $2^5$ : 4 – 3
    = 12 + 3. $2^5$ : $2^2$ – 3
    = 12 + 3. $2^3$ – 3
    = 12 + 3. 8 – 3
    = 12 + 24 – 3
    = 36 – 3
    = 33
    b) 25. 8 – 15. 5 + 160 : 16 – 10
    = 5. 5. 8 – 15. 5 + 10 – 10
    = 5. 40 – 15. 5 + ( 10 – 10 )
    = 5. ( 40 – 15 ) + 0
    = 5. 25
    = 125

    a, 12 + 3 . 2^5 : 4 – 3
    = 12 + 3 . 32 : 4 – 3
    = 12 + 96 : 4 – 3
    = 12 + 24 – 3
    = 36 – 3
    = 33
    b, 25 . 8 – 15 . 5 + 160 : 16 – 10
    = 200 – 75 + 10 – 10
    = 125 + 0
    = 125
