Answer 1

3,53×100-1,74×10=353-17,4=335,6
2,34×0,2-0,5×0,14=0,46×0,07=0,39
0,00153×10^4-0,0014×10^4=(0,00153-0,0014)×10^4=13×10^-1=1,3
0,15×10^5-0,15×10^4=(1,5-0,15)×10^4=1,35×10^4=135×10^2=13500
1,3×10^4-0,24×10^3+3,4×10^2=(13-0,24)×10^3+3,4×10^2=12,76×10×10^2+3,4×10^2=(127,6+3,4)×10^2=131×10^2=13100
5342÷1000-14,73÷10=2671/500-1473/100÷10=5432-1473totul supra/1000=3869/1000=3,869
