Question

write + or - in the circles. 8 〇 2 = 2 〇 4 3 〇 1 〇 4 = 4 〇 8 〇 6

Explanation:

Step1: Analyze the first equation

Try different operations. $8 - 2=6$ and $2 + 4 = 6$.

Step2: Analyze the second equation

Try operations. $3 + 1+4 = 8$ and $4 + 8-6 = 6$ doesn't work. But $3 - 1+4=6$ and $4 + 8 - 6=6$.

Answer:

$8 - 2 = 2 + 4$; $3 - 1+4 = 4 + 8 - 6$
