Explicación paso a paso:

1.- \left(-1\right)\left(1\right)\left(-2\right)-\left(7\right)\left(3\right)\left(-1\right)-\left(2\right)\left(-5\right)

=2-\left(7\right)\left(3\right)\left(-1\right)-\left(2\right)\left(-5\right)

=2-\left(-21\right)-\left(2\right)\left(-5\right)

=2-\left(-21\right)-\left(-10\right)

=33

2.- \left(5\right)\left(-2\right)\left(-1\right)-\left(-1\right)\left(-3\right)-\left(-2\right)\left(5\right)\left(-1\right)

=10-\left(-1\right)\left(-3\right)-\left(-2\right)\left(5\right)\left(-1\right)

=10-3-\left(-2\right)\left(5\right)\left(-1\right)

=10-3-10

=-3

3.- \left(20\right)\left(-2\right)+\left(-4\right)\left(3\right)

=-40+\left(-4\right)\left(3\right)

=-40-12

=-52

4.- \left(2\right)\left(-2\right)+\left(-4\right)\left(3\right)

=-4+\left(-4\right)\left(3\right)

=-4-12

=-16

5.- \left(-15\right)\left(4\right)-1

=-60-1

=-61

6.- \left(-6\right)\left(-2\right)\left(1\right)+\left(-2\right)

=12+\left(-2\right)

=10
