400 + 86

Decomposition into decimal digits (or separating out into place values).

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

405 centimeters because 4m equals 400 cm and plus 5cm equals 405cm

(((800 plus 400) plus 400) plus 500) plus 500 = 2600
