\(35+98=\left(35-2\right)+\left(98+2\right)=33+100=133\)
\(46+29=\left(46+4\right)+\left(29-4\right)=50+25=75\)
35 + 98 = (35 - 2) + (98 + 2) = 33 + 100 = 133.
46 + 29 = (46 - 1) + (29 + 1) = 45 + 30 = 75.
35+98=(35-2)+(98+2)=33+100=133 46+29=(46-1)+(29+1)=45+30=75
Ta có:
35 + 98 = ( 35 - 2 ) + ( 98 + 2 ) = 33 + 100 = 133
46 + 29 = ( 46 + 4 ) + ( 29 - 4 ) = 50 + 25 = 75
35 + 98 = (35 - 2) + (98 + 2) = 33 + 100 = 133
46 + 29 = (46 - 1) + (29 + 1) = 45 + 30 = 75
