Which two signs should be interchanged in the following equation to make it correct?
$$24 \div 8 - 5 \times 5 + 3 = 13$$
$$24 \div 8 - 5 \times 5 + 3 = 13$$
$$\Rightarrow 3-5\times5+3 =-19Â \neq 13$$
So, after interchanging the sign of $$\times$$ and $$+$$
$$\Rightarrow 24 \div 8 - 5 +5 \times 3 = 13$$
$$\Rightarrow 3 - 5 +5 \times 3 = 13$$
$$\Rightarrow 3 - 5 +15 = 13$$
$$\Rightarrow - 5 +18 = 13$$
$$\Rightarrow - 13 = 13$$
Hence, after interchanging the sign of $$\times$$ and $$+$$ will get the correct.
