To answer this question, it will be easier to split the sentences into multiple part like this:
1. "4hundred thousand" mean 4* 100,000= 400,000
2. "13 thousand" mean 13*1,000= 13,000
3. "11 hundred" mean 11*100=1,100
4. "4 ones" mean 4 * 1= 4
Then you add them all into: 400,000+13,000 + 1,100 + 4= 414,104
