order(id,currency_code,ex_rate_with_base,status,total_in_base_currency,status)

currency(currency_code,symbol,currency_name,currency_value,ex_rate_with_base,status)

order_list(id,order_id,product_code,qty,unit_price_in_base_currency,status)

I want the following output: Here I want to multiply the 'ex_rate_with_base' field of 'order' table with 'unit_price' of 'order_list' table using eloquent
