The answer is 18,785,024
900 + 100 = 1000
1000 + 400 - 300 = 1100
900
600 + 400 = 1000
400 + 500 = 900
900
Oh, dude, that's like basic math 101. So, 400 plus 1000 equals 1400. It's like, not rocket science or anything.
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
900
It is 1931
4,700.
