A Short Math Prayer for Everyone

I got this math prayer from a class I observed last year. Here in our country, it is customary to start class with a prayer. Here are some of the prayers that I’ve collected.

Dear God,

May we, through your blessings,

add purity to the world,

subtract evil from our lives,

multiply Your good news,

and divide Your gifts and share them with others.

Amen.

I suppose that students are really prayerful especially before a math exam.  I can speak from experience. I always pray before taking a math exam when I was still a student.

Prayer 2

Almighty God
We pray to You
To have our joys added
Sorrows subtracted
Friends multiplied
Love divided
And problems be solved
Amen…

 

Prayer 3

We thank you a hundredfold for the love and care that you have given us. May we return to you your good works by multiplying it with love and respect, adding more faith, subtracting worldly behavior and evil works, and dividing your given talents to others, so we can sum them all and be united as one in your family. In this we pray, Amen.
