1 27 + 3 · 5 – 16 =

27 + 3 · 5 – 16 = 27 + 15 − 16 = 26

2 27 + 3 – 45 : 5 + 16=

27 + 3 – 45 : 5 + 16 = 37

3 (2 · 4 + 12) (6 − 4) =

(2 · 4 + 12) (6 − 4) = (8 + 12) (2) = 20 · 2 = 40

4 3 · 9 + (6 + 5 – 3) – 12 : 4 =

3 · 9 + (6 + 5 – 3) – 12 : 4 = 27 + 8 – 3 = 32

5 2 + 5 · (2 ·3) ³ =

2 + 5 · (2 ·3) ³ = 2 + 5 · (6) ³ = 2 + 5 · 216 = 2 + 1080 = 1082

6 440 − [30 + 6 (19 − 12)] =

440 − [30 + 6 (19 − 12)] = 440 − (30 + 6 · 7) ] = 440 − (30 +

42) =

= 440 − (72) = 368

7 2{4[7 + 4 (5 · 3 − 9) ] − 3 (40 − 8)} =

= 2{4[7 + 4 (15 − 9) ] − 3 (40 − 8)}=

= 2[4 (7 + 4 · 6) − 3 (32) ] = 2[4 (7 + 24) − 3 (32) ]=

2[4 (31) − 3 (32) ]= 2 (124 − 96)= 2 (28)= 56
