The simplest summation of Mr. Ford's life and work may be that he did exactly what he wanted, and seemingly knew everyone.

This permissive gating is more than a matter of simple summation, however.

The aggregation process did not distinguish between simple summation or average calculations, and more complex non-commutative calculations.

This means that higher order patterns of a whole functional system, such as an ecosystem, cannot be predicted or understood by a simple summation of the parts.

This introduces error but allows combination of primary and referred secondary resistances and reactances by simple summation as two series impedances.

In that case, the integration of the accelerations can be well approximated by relatively simple summations.

"She made the choice of how she would die," Nathan said in simple summation.

In particular, the Rayleigh-Carson reciprocity theorem becomes a simple summation:

The calculation couldn't be very difficult, no more than a formula and a few simple summations.

This is arrived at by simple summation of the sequence.
