When look at Buzzard’s example of 2+2=4, in our heads, we turn the string that is 2+2 into the integer that is 4. Then, we can compare the integers that now exist on both sides of the equal sign.

Many of them avoid the equal sign, hoping to promote a looser relationship of “equivalence” instead. It's been controversial.
