  • Paper

Lucky Larry's teacher asked him to substitute numbers for aa, bb, cc, dd, and ee in the expression a−(b−(c−(d+e)))a-(b-(c-(d+e))) and evaluate the result. Larry ignored the parentheses but added and subtracted correctly and obtained the correct result by coincidence. The numbers Larry substituted for aa, bb, cc, and dd were 11, 22, 33, and 44, respectively. What number did Larry substitute for ee?
