Solve -1^2-left(1^3-1-0*42/0.21right)left(-19.75/32+11.75/32right)

$$- { 1 }^{ 2 } - \left( { 1 }^{ 3 } -1- \frac{ 0 \cdot 42 }{ 0.21 } \right) \left( -19.7 \frac{ 5 }{ 32 } +11.7 \frac{ 5 }{ 32 } \right)$$

Evaluate

$$-1$$

Solution Steps

Calculate 1 to the power of 2 and get 1.

$$-1-\left(1^{3}-1-\frac{0\times 42}{0.21}\right)\left(-\frac{19.7\times 32+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Calculate 1 to the power of 3 and get 1.

$$-1-\left(1-1-\frac{0\times 42}{0.21}\right)\left(-\frac{19.7\times 32+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Subtract 1 from 1 to get 0.

$$-1-\left(-\frac{0\times 42}{0.21}\right)\left(-\frac{19.7\times 32+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Multiply 0 and 42 to get 0.

$$-1-\left(-\frac{0}{0.21}\right)\left(-\frac{19.7\times 32+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Zero divided by any non-zero number gives zero.

$$-1-0\left(-\frac{19.7\times 32+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Multiply 19.7 and 32 to get 630.4.

$$-1-0\left(-\frac{630.4+5}{32}+\frac{11.7\times 32+5}{32}\right)$$

Add 630.4 and 5 to get 635.4.

$$-1-0\left(-\frac{635.4}{32}+\frac{11.7\times 32+5}{32}\right)$$

Expand \frac{635.4}{32} by multiplying both numerator and the denominator by 10.

$$-1-0\left(-\frac{6354}{320}+\frac{11.7\times 32+5}{32}\right)$$

Reduce the fraction \frac{6354}{320} to lowest terms by extracting and canceling out 2.

$$-1-0\left(-\frac{3177}{160}+\frac{11.7\times 32+5}{32}\right)$$

Multiply 11.7 and 32 to get 374.4.

$$-1-0\left(-\frac{3177}{160}+\frac{374.4+5}{32}\right)$$

Add 374.4 and 5 to get 379.4.

$$-1-0\left(-\frac{3177}{160}+\frac{379.4}{32}\right)$$

Expand \frac{379.4}{32} by multiplying both numerator and the denominator by 10.

$$-1-0\left(-\frac{3177}{160}+\frac{3794}{320}\right)$$

Reduce the fraction \frac{3794}{320} to lowest terms by extracting and canceling out 2.

$$-1-0\left(-\frac{3177}{160}+\frac{1897}{160}\right)$$

Since -\frac{3177}{160} and \frac{1897}{160} have the same denominator, add them by adding their numerators.

$$-1-0\times \frac{-3177+1897}{160}$$

Add -3177 and 1897 to get -1280.

$$-1-0\times \frac{-1280}{160}$$

Divide -1280 by 160 to get -8.

$$-1-0\left(-8\right)$$

Multiply 0 and -8 to get 0.

$$-1-0$$

Subtract 0 from -1 to get -1.

$$-1$$

Factor

$$-1$$
