Answer 1

a) 10 x 100 - (864:2 + 336:3+ 1296:4) =

1000 - (432 + 112 + 324) =

1000 - 868 = 132

b) (777:7+464:2-969:3+888:4): 2-194:2 =

(111 + 232 - 323 + 222) :2 - 97 =

242 :2 -97=

121 -97 = 24

I) (468:2 +848:4+646:2 +666:6) + 10:5=

(234 +212 +323 +111) + 2=

880 +2 = 882

d) (848:4-448:4 + 696:3+402:3): 2 x 3 =

(212 -112 +232 +134):2 ×3=

466: 2×3=

233×3=699

e) 17 x 20 - (968:4 +963:3+ 866:2):3=

340 -(242 +321 +433):3 =

340 - 996:3 =

340 - 332 = 8
