Question

+
$+ \times + = \\ - \times - = \\ - \times + = \\ + \times - =$
please answer these formulaes fast

Answer 1

${\red{\boxed{\boxed{\bold{\huge{Answer:-}}}}}}$

$+ \times + = + \\ - \times - = + \\ - \times + = - \\ + \times - = -$

${\red{\underline{\underline{\bold{Examples:-}}}}}$

• (+2)×(+2)=4

• (-2)×(-2)=4

• (-2)×(+2)=-4

• (+2)×(-2)=-4

Answer 2

$\huge{ \underline{ \overline{ \mid{ \mathfrak{ \purple{ \: \: ANSWER \: \: } \mid}}}}}$

$\bold{1. \: \: \red{+} \times \red{+ } = \red{ +} } \\ \\ \bold{ 2. \: \: \red{ - } \times \red{-} = \red{ +} }\\ \\ \bold{ 3. \: \: \red{-} \times \red{+} = \red{-} }\\ \\ \bold{4. \: \: \red{ + } \times \red{ -} = \red{ - }}$

$\underline{ \mathfrak{ \red{\: \: Examples : \mapsto \: \: }}}$

$\tt{1. \: \: ( + 2) \times ( + 2 ) = 4} \\ \\ \tt{2. \: \: ( - 2) \times ( - 2) = 4} \\ \\ \tt{3. \: ( - 2) \times ( + 2) = - 4} \\ \\ \tt{4. \: \: ( + 2) \times ( - 2) = - 4}$
