The same decimal series, with the five final forms promoted into the next block of hundreds: ך = 500, ם = 600, ן = 700, ף = 800, ץ = 900. אלהים = 1+30+5+10+600 = 646 against 86 in hechrachi; אדם = 1+4+600 = 605 against 45.
Meaning
Mispar gadol is used where the plain value is too small to carry a reading, and it supplies the 500–900 band that lets the numeral system run to 900 on twenty-seven letter-shapes. Because a final appears only at the end of a word, the same root can carry two very different 'great' values according to how it is written, which is both the method's freedom and its standing weakness.
