Answer 1

Answer:

$4 \: and \: - 6 \: \: \: \\ = 4 + ( - 6) \\ \\ = 4 - 6 \\ \\ = - 2$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$( - 7) + ( - 5) \\ \\ = - 7 - 5 \\ \\ - 12$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$6+ 9 \\ \\ = 15$

$6 + ( - 7) \\ \\ = 6 - 7 \\ \\ = - 1$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$( - 2) + ( - 9) \\ \\ = - 2 - 9 \\ \\ = - 11$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$3 + ( - 3) \\ \\ = 3 - 3 \\ \\ = 0$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$( - 5) + 3 \\ \\ = - 5 + 3 \\ \\ = - 2$

$\pink{⊱⋅ ─────────────────── ⋅⊰}$

$5 + ( - 3) \\ \\ = 5 - 3 \\ \\ = 2$
