561 x 261

= (500 + 60 + 1) x 261

= 500 x 261 + 60 x 261 + 1 x 261

= 130500 + 15660 + 261

= 146160 + 261

= 146421

578 x 264

= (500 + 70 + 8) x 264

= 500 x 264 + 70 x 264 + 8 x 264

= 132000 + 18480 + 2112

= 150480 + 2112

= 152592

587 x 301

= (500 + 80 + 7) x 301

= 600 x 301 + 80 x 301 + 7 x 301

= 150500 + 24080 + 2107

= 174580 + 2107

= 176687

679 x 333

= (600 + 70 + 9) x 333

= 600 x 333 + 70 x 333 + 9 x 333

= 199800 + 23310 + 2997

= 223110 + 2997

= 226107

685 x 345

= (600 + 80 + 5) x 345

= 600 x 345 + 80 x 345 + 5 x 345

= 207000 + 27600 + 1725

= 234600 + 1725

= 236325
