Work: Calculate the value of equation 17.8×2.83+(17.8-9.8)×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63 .
Question type: Mathematical calculation
Solution:
17.8×2.83+(17.8-9.8)×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×0.41+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×0.41+8×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×0.41+8×15.6+9.3×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×0.41+8×15.6+9.3×0.08+8.1×7.39+(17.9-9.8)×0.63
=17.8×2.83+8×0.41+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
=50.374+8×0.41+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
=50.374+3.28+8×15.6+9.3×0.08+8.1×7.39+8.1×0.63
=50.374+3.28+124.8+9.3×0.08+8.1×7.39+8.1×0.63
=50.374+3.28+124.8+0.744+8.1×7.39+8.1×0.63
=50.374+3.28+124.8+0.744+59.859+8.1×0.63
=50.374+3.28+124.8+0.744+59.859+5.103
=53.654+124.8+0.744+59.859+5.103
=178.454+0.744+59.859+5.103
=179.198+59.859+5.103
=239.057+5.103
=244.16
Answer:17.8×2.83+(17.8-9.8)×(3.24-2.83)+(17.8-9.8)×15.6+(19.1-9.8)×0.08+(17.9-9.8)×7.39+(17.9-9.8)×0.63=244.16
