判断对错

$\text{[math]}$

举一反三

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

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

$\text{[math]}$ + $\text{[math]}$ = 1- $\text{[math]}$ = $\text{[math]}$ - $\text{[math]}$ =

0.9×100= $\text{[math]}$ + $\text{[math]}$ = 0.64÷16=

10-9.12= 0.7÷3.5= 0.8×125=

67+33= 56-25= 23+66= 398+109≈

440-170= 150+90= 400×5= 603-189≈

300-210= 0×616= 125×4= 198×3≈

$\text{[math]}$ + $\text{[math]}$ = $\text{[math]}$ - $\text{[math]}$ = 1- $\text{[math]}$ = 304×6≈
