口算．

$\text{[math]}$ =	$\text{[math]}$ =
$\text{[math]}$ =	$\text{[math]}$ =

举一反三

$\text{[math]}$

$\text{[math]}$ + $\text{[math]}$ = $\text{[math]}$ - $\text{[math]}$ = $\text{[math]}$ + $\text{[math]}$ = $\text{[math]}$ + $\text{[math]}$ =

$\text{[math]}$ - $\text{[math]}$ = 3- $\text{[math]}$ = $\text{[math]}$ - $\text{[math]}$ = $\text{[math]}$ - $\text{[math]}$ =

$\text{[math]}$

$\text{[math]}$ {#blank#}1{#/blank#}

$\text{[math]}$ {#blank#}2{#/blank#}

根据图形与算式，我发现：{#blank#}3{#/blank#}。
