d)6[3+3x(4+4x225)]
e)8x{2+10x[542+2x(2+2x542)]}
f)(12x25-5x13)+1000:8-100:4

Answer 1

a) 16+16x2=16+32=48                                                                                        b) 9+3x457= 9+1371=1380                                                                                  c) 2x(1400-546)= 2x854=1708
d)225x4=900+4=904x3 =2712+3=2715
e) 2x542=1084+2=1086x2 =2172+542=2714 x 10 = 27140 +2 = 27142x 8 =217136
f) 12x 25 = 300 - 5x 13 = 300-65 = 235 + 1000:8 =235+ 125 - 100 : 4 =360 - 25 = 35

Answer 2

a) 16x2=32+16=48
b)3x457=1371+9=1380
c)1400-546=854x2=1708
d)225x4=900+4=904x3 =2712+3=2715
e) 2x542=1084+2=1086x2 =2172+542=2714 x 10 = 27140 +2 = 27142x 8 =217136
f) 12x 25 = 300 - 5x 13 = 300-65 = 235 + 1000:8 =235+ 125 - 100 : 4 =360 - 25 = 35
