How to complete Calculations from prior questions

How to complete Calculations from prior questions

I've added this: 

${Q-A[SUM]}+${Q-T[SUM]}+${Q-AJ[SUM]}+${Q-BF[SUM]}+${Q-BU[SUM]}+${Q-CS[SUM]}+${Q-DU[SUM]}+${Q-EN[SUM]}

to a Heading/Description (text) question. I thought I had read that the result to this calculation would show when operators are used. Instead, it is displaying the entire expression, each variable sum and each operator with no total.

Can someone please help me show a final sum/tally, based on 10 variables?

Much appreciation,
