Answer:
2600
Step-by-step explanation:
first you would round them to the nearest hundred. this means that if the figure in the tens column is greater than or equal to 5 you would round up. if it is less than 5 you round down
so 1400+400+800=
then you would add them up
so 1400+400+800=2600
1400+400=1800
1800+800=2600
