Evaluate

$$22067261648773017421254609399185653$$

Solution Steps

Calculate 7 to the power of 2 and get 49.

$$49\left(2-3+6\right)-64^{18}\left(6+\left(3+2\left(4+2\right)^{2}-1\right)\left(-1\right)\right)$$

Subtract 3 from 2 to get -1.

$$49\left(-1+6\right)-64^{18}\left(6+\left(3+2\left(4+2\right)^{2}-1\right)\left(-1\right)\right)$$

Add -1 and 6 to get 5.

$$49\times 5-64^{18}\left(6+\left(3+2\left(4+2\right)^{2}-1\right)\left(-1\right)\right)$$

Multiply 49 and 5 to get 245.

$$245-64^{18}\left(6+\left(3+2\left(4+2\right)^{2}-1\right)\left(-1\right)\right)$$

Calculate 64 to the power of 18 and get 324518553658426726783156020576256.

$$245-324518553658426726783156020576256\left(6+\left(3+2\left(4+2\right)^{2}-1\right)\left(-1\right)\right)$$

Add 4 and 2 to get 6.

$$245-324518553658426726783156020576256\left(6+\left(3+2\times 6^{2}-1\right)\left(-1\right)\right)$$

Calculate 6 to the power of 2 and get 36.

$$245-324518553658426726783156020576256\left(6+\left(3+2\times 36-1\right)\left(-1\right)\right)$$

Multiply 2 and 36 to get 72.

$$245-324518553658426726783156020576256\left(6+\left(3+72-1\right)\left(-1\right)\right)$$

Add 3 and 72 to get 75.

$$245-324518553658426726783156020576256\left(6+\left(75-1\right)\left(-1\right)\right)$$

Subtract 1 from 75 to get 74.

$$245-324518553658426726783156020576256\left(6+74\left(-1\right)\right)$$

Multiply 74 and -1 to get -74.

$$245-324518553658426726783156020576256\left(6-74\right)$$

Subtract 74 from 6 to get -68.

$$245-324518553658426726783156020576256\left(-68\right)$$

Multiply 324518553658426726783156020576256 and -68 to get -22067261648773017421254609399185408.

$$245-\left(-22067261648773017421254609399185408\right)$$

The opposite of -22067261648773017421254609399185408 is 22067261648773017421254609399185408.

$$245+22067261648773017421254609399185408$$

Add 245 and 22067261648773017421254609399185408 to get 22067261648773017421254609399185653.
