MUSLIMS usually use the mathematical equation "1+1+1=1" to show their objection to the Holy Trinity being 3 PERSONS in 1 GOD ... and to show that the belief is "wrong."
Sadly, MUSLIMS are USING the WRONG EQUATION.
ADDITION is USED for PHYSICAL MATTER.
GOD, the HOLY TRINITY, is NOT PHYSICAL. GOD is SPIRITUAL and GOD is POWER.
In MATH, POWER is expressed through MULTIPLICATION.
So, in relation to GOD, the RIGHT EQUATION is:
GOD BE PRAISED!
