[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]
(1) a + b = ?
- Given, a = - 1 & b = 6.
- So, a + b = ?
[tex] \sf \: a + b = ? \\ \\ \sf \: Substitute \: the \: values \: of \: a \: and \: b \\ \\ \sf a + b \\ \sf \dashrightarrow( - 1) + (6) \\ = \large \boxed{\mathfrak{ 5}}[/tex]

(2) ab = ?
- Given, a = - 1 & b = 6
- So, ab = ?
[tex] \sf \: ab \: = ? \\ \\ \sf \: Substitute \: the \: values \: of \: a \: and \: b \\ \\ \sf \: ab \\ \dashrightarrow \sf( - 1)(6) \\ \dashrightarrow \sf- 1 \times 6 \\ = \boxed{\mathfrak{ \bold- 6}}[/tex]
