simplify (-5.2)+(-3.8)-{(-1.2)-[(-0.5)-(-0.7)]}

simplify

(- 5.2) + (- 3.8) - {(- 1.2) - [(- 0.5) - (- 0.7)]}

- 7.6

Solution steps

(- 5.2) + (- 3.8) - ((- 1.2) - ((- 0.5) - (- 0.7)))

(- 5.2) + (- 3.8) - ((- 1.2) - ((- 0.5) - (- 0.7))) = - 5.2 - 3.8 - ((- 1.2) - ((- 0.5) - (- 0.7)))

= - 5.2 - 3.8 - (- 1.2 - (- 0.5 - (- 0.7)))

Apply rule:

a - (- b) = a + b

- 0.5 - (- 0.7) = - 0.5 + 0.7

= - 5.2 - 3.8 - (- 1.2 - (- 0.5 + 0.7))

Subtract the numbers:

- 5.2 - 3.8 = - 9

= - 9 - (- 1.2 - (- 0.5 + 0.7))

- (- 1.2 - (- 0.5 + 0.7)) = 1.4

= - 9 + 1.4

Add the numbers:

- 9 + 1.4 = - 7.6

= - 7.6

\frac{6 x - 12 y}{4 y - 2 x}

m^{2} - 2 m^{2} - 7 m^{2}

(A - 1)^{2} + (B - 2)^{2}
