(-10) + (-7) + (-4) + (-1) + (+4) + (+7) =

Answer 1

$\sf \left(+8\right)\:+\:\left(-3\right)\:+\:\left(-8\right)\:+\:\left(-1\right)\:+\:\left(+2\right)\\\\\\\sf \left(8\right)-3+\left(-8\right)+\left(-1\right)+\left(2\right)\\\\\\\sf 5+\left(-8\right)+\left(-1\right)+\left(2\right)\\\\\\\sf 5-8+\left(-1\right)+\left(2\right)\\\\\\\sf -3+\left(-1\right)+\left(2\right)\\\\\\\sf -3-1+\left(2\right)\\\\\\\sf -4+\left(2\right)\\\\\\=-2$

$\sf \left(-10\right)\:+\:\left(-7\right)\:+\:\left(-4\right)\:+\:\left(-1\right)\:+\:\left(+4\right)\:+\:\left(+7\right)\\\\\\\sf \left(-10\right)-7+\left(-4\right)+\left(-1\right)+\left(4\right)+\left(7\right)\\\\\\\sf -17+\left(-4\right)+\left(-1\right)+\left(4\right)+\left(7\right)\\\\\\\sf -17-4+\left(-1\right)+\left(4\right)+\left(7\right)\\\\\\\sf -21+\left(-1\right)+\left(4\right)+\left(7\right)\\\\\\\sf -21-1+\left(4\right)+\left(7\right)\\\\\\\sf -22+\left(4\right)+\left(7)$

$\sf -18+\left(7\right)\\\\\\=-11$
