Singapore MathⓋ
A discount of not less than 19 percent for any buyer of math titles in Singapore, who has been jabbed by WHO-approved vaccines, as long as they show proof of their inoculation at the time of purchase.
To encourage vaccination among the population, especially among those who wished not to be inoculated because of potential side effects or premature death, local publishers in Singapore are resorting to creative marketing to promote a number of their dated Singapore MathⓋ titles.
