The chart below records the sale at the stationery shop by Valentina's father, month by month, from January to April. She decided to calculate the sale by putting the months together.
January and February: 400+500=900, since 4 hundreds+5 hundreds = 9 hundreds and 9 hundreds =900 units.
February and March: 500+600=1100, since 5 hundreds+6 hundreds =11 hundreds and 11 hundreds =1100.
