its funny how people never realized that calculators only do what they are told, unless you insist on the calculator doing 10 * 10 and then 10 * 10 and then putting those two results together. :)
In standard mode Windows calculator does the operations in order (just like most handheld non-scientific calculators). You're doing (10 * 10), ((10 * 10) + 10), (((10 * 10) + 10) * 10).
