SUMMARY
The calculation presented involves determining the number of significant figures in the expression (11.13 - 2.6) * 10^4 + (103.05 + 16.9) * 10^-6. The result of the subtraction (11.13 - 2.6) yields 8.53, which has three significant figures, while the addition (103.05 + 16.9) results in 119.95, which has four significant figures. The final result must be expressed with the least number of significant figures from the operations involved, leading to a conclusion of three significant figures for the overall calculation.
