Question

Help I don’t understand this

Answer 1

1 row. number = 473

100 more = 573 100 less = 373

10 more = 483 10 less = 463

1 more = 474 1 less = 472

2nd row. number will be 398 - 100 = 298

100 more = 398 100 less = 198

10 more = 308 10 less = 288

1 more = 299 1 less = 297

3rd row. number will be 890 + 10 = 900

100 more = 1000 100 less = 800

10 more = 910 10 less = 890

1 more = 901 1 less = 899
