$2438.79 - 1233.99 + 399.99 = ? + 989.99$

$958 \times 21 \div 4 = ?$

$\sqrt{?} \%$ of $160 = 128 \div 4$

If in a long division sum,the dividend is $380606$ and the successive remainders from the first to the last are $434, 125,$ and $413,$ then the divisor is:

On dividing a number by $56$,we get $29$ as remainder. On dividing the same number by $8$,what will be the remainder?

$4433.764 - 2211.993 - 1133.667 + 3377.442 = ?$
