A simple algorithm of 0.36 × 1.5-0.45 Don't copy, just answer what you think


0.36x1.5-0.3x1.5=1.5x(0.36-0.3)=1.5x0.06=0.09



4.5 × 12.6-0.26 × 45 how to simplify the algorithm?


4.5×12.6-0.26×45
=4.5×12.6-2.6×4.5
=4.5×(12.6-2.6)
=4.5×10
=45



A simple algorithm of 14.5 × 0.1 + 1.45 × 9


14.5×0.1+1.45×9
=1.45×(1+9)
=1.45×10
=14.5
