[1/1 Formula]
    Work: Calculate the value of equation 17.8×2.31+19.2×3.47+17.8×(6.88-3.47-2.31)+(17.8-9.8)×(17.37-6.88+3.47+2.31)+(17.9-9.8)×3.59 .
    Question type: Mathematical calculation
    Solution:
          17.8×2.31+19.2×3.47+17.8×(6.88-3.47-2.31)+(17.8-9.8)×(17.37-6.88+3.47+2.31)+(17.9-9.8)×3.59
        =17.8×2.31+19.2×3.47+17.8×1.1+(17.8-9.8)×(17.37-6.88+3.47+2.31)+(17.9-9.8)×3.59
        =17.8×2.31+19.2×3.47+17.8×1.1+8×(17.37-6.88+3.47+2.31)+(17.9-9.8)×3.59
        =17.8×2.31+19.2×3.47+17.8×1.1+8×16.27+(17.9-9.8)×3.59
        =17.8×2.31+19.2×3.47+17.8×1.1+8×16.27+8.1×3.59
        =41.118+19.2×3.47+17.8×1.1+8×16.27+8.1×3.59
        =41.118+66.624+17.8×1.1+8×16.27+8.1×3.59
        =41.118+66.624+19.58+8×16.27+8.1×3.59
        =41.118+66.624+19.58+130.16+8.1×3.59
        =41.118+66.624+19.58+130.16+29.079
        =107.742+19.58+130.16+29.079
        =127.322+130.16+29.079
        =257.482+29.079
        =286.561

    Answer:17.8×2.31+19.2×3.47+17.8×(6.88-3.47-2.31)+(17.8-9.8)×(17.37-6.88+3.47+2.31)+(17.9-9.8)×3.59=286.561
