Answer 1

22003 – 22002 – 22001 - … - 22 – 2 – 1 = 22002(2 - 1) – 22001 - …. – 22 – 2 – 1 = 22001(2 - 1) – 22000 - ….- 22 – 2 – 1 = 22(2-1) – 2 – 1 = 2(2 - 1) – 1=1

Answer 2

Для того чтобы решить данное выражение, нужно провести операции вычитания поочередно для каждого числа, начиная с числа 22003 и заканчивая -2 и -1.

22003 - 22002 = 1 1 - 22001 = -22000 -22000 - 22000 = -44000 -44000 - 22000 = -66000 -66000 - 22000 = -88000 -88000 - 22000 = -110000 -110000 - 22000 = -132000 -132000 - 22000 = -154000 -154000 - 22000 = -176000 -176000 - 22000 = -198000 -198000 - 22000 = -220000 -220000 - 22000 = -242000 -242000 - 22000 = -264000 -264000 - 22000 = -286000 -286000 - 22000 = -308000 -308000 - 22000 = -330000 -330000 - 22000 = -352000 -352000 - 22000 = -374000 -374000 - 22000 = -396000 -396000 - 22000 = -418000 -418000 - 22000 = -440000 -440000 - 22000 = -462000 -462000 - 22000 = -484000 -484000 - 22000 = -506000 -506000 - 22000 = -528000 -528000 - 22000 = -550000 -550000 - 22000 = -572000 -572000 - 22000 = -594000 -594000 - 22000 = -616000 -616000 - 22000 = -638000 -638000 - 22000 = -660000 -660000 - 22000 = -682000 -682000 - 22000 = -704000 -704000 - 22000 = -726000 -726000 - 22000 = -748000 -748000 - 22000 = -770000 -770000 - 22000 = -792000 -792000 - 22000 = -814000 -814000 - 22000 = -836000 -836000 - 22000 = -858000 -858000 - 22000 = -880000 -880000 - 22000 = -902000 -902000 - 22000 = -924000 -924000 - 22000 = -946000 -946000 - 22000 = -968000 -968000 - 22000 = -990000 -990000 - 22000 = -1012000

Таким образом, выражение 22003 - 22002 - 22001 - ... - 22 - 2 - 1 равно -1 012 000.
