Judge the identity

Answer

$2 \times 1 = 2$

$ $ TRUE $ $

Judge the identity

$2 \color{#FF6800}{ \times } \color{#FF6800}{ 1 } = 2$

$ $ Multiplying any number by 1 does not change the value $ $

$\color{#FF6800}{ 2 } = 2$

$\color{#FF6800}{ 2 } = \color{#FF6800}{ 2 }$

$ $ Since the values to calculate for all terms are equal, this expression is an identity $ $

$ $ TRUE $ $
