400 + 900 + 1000 = 2300
The answer is 18,785,024
1000 + 400 - 300 = 1100
900 + 100 = 1000
600 + 400 = 1000
900
400 + 500 = 900
400 plus 1000 equals 1400. This is because when you add 400 and 1000 together, you are combining the two quantities to get a total sum of 1400. In mathematical terms, this operation can be represented as 400 + 1000 = 1400.
900
To estimate a number you round it up to easier number so 387 would be 400. 945 would be 950 and 1024 would be 1030. so 400 and 950 would be 1350 plus 1030 equals 2380 you could even round it up easier so 400 plus 900 and 1000 equals 2300
It is 1931
900
2 + 400/1000 = 2.4 litres or 2400 millilitres.
