Work: Calculate the value of equation 17.8×5.24+19.2×1.67+17.8×(8.33-1.67-5.24)+(17.8-9.8)×(17.49-8.33+1.67+5.24)+(17.9-9.8)×4.3 .
Question type: Mathematical calculation
Solution:
17.8×5.24+19.2×1.67+17.8×(8.33-1.67-5.24)+(17.8-9.8)×(17.49-8.33+1.67+5.24)+(17.9-9.8)×4.3
=17.8×5.24+19.2×1.67+17.8×1.42+(17.8-9.8)×(17.49-8.33+1.67+5.24)+(17.9-9.8)×4.3
=17.8×5.24+19.2×1.67+17.8×1.42+8×(17.49-8.33+1.67+5.24)+(17.9-9.8)×4.3
=17.8×5.24+19.2×1.67+17.8×1.42+8×16.07+(17.9-9.8)×4.3
=17.8×5.24+19.2×1.67+17.8×1.42+8×16.07+8.1×4.3
=93.272+19.2×1.67+17.8×1.42+8×16.07+8.1×4.3
=93.272+32.064+17.8×1.42+8×16.07+8.1×4.3
=93.272+32.064+25.276+8×16.07+8.1×4.3
=93.272+32.064+25.276+128.56+8.1×4.3
=93.272+32.064+25.276+128.56+34.83
=125.336+25.276+128.56+34.83
=150.612+128.56+34.83
=279.172+34.83
=314.002
Answer:17.8×5.24+19.2×1.67+17.8×(8.33-1.67-5.24)+(17.8-9.8)×(17.49-8.33+1.67+5.24)+(17.9-9.8)×4.3=314.002
