Answer 1

a) 30×15+44=450+444=894
     375-17×20= 375-340= 35
b) 40×(189-95)=40×94= 3760
    (125+674)×= 799×7=5593
c)15×60-12×60= 60×(15-12)=60×3= 180
    6×(2+18-10)= 6×10=60
d) 12×9+4×150= 108+600= 708
     392×10-(4×5+16)= 3920-(20+16= 3920-36= 3884

Answer 2

30 ori 15 + 444 =450 +444 =894
375-17 •20=375-340=35
40 ori ( 186 - 95 )=40 ori 91=3640
(128+674)ori7=802ori7=5614
15 ori 60 - 12 ori 60 = 900 - 720 =280
6 ori (2+18-10)= 6 ori (20 - 10 )= 6 ori 10 = 60
12 ori 9 + 4 ori 150 =108+600= 708
392 ori 10 - (4 ori 5 + 16 )=3920-(20+16)=3920-36=3884
