Count the batteries. Now choose the best answer. \(20 \, + \, 0 \, = \, x\)

\(2 \, tens \, + \, 0 \, ones \, = \, 20\)

\(0 \, tens \, + \, 2 \, ones \, = \, 20\)

\(0 \, tens \, + \, 2 \, ones \, = \, 14\)

\(2 \, tens \, + \, 0 \, ones \, = \, 17\)

\(2 \, tens \, + \, 0 \, ones \, = \, 20\)

Count the dolls. Now choose the best answer. \(4 \, + \, 4 \, = \, x\)

\(0 \, tens \, + \, 4 \, ones \, = \, 4\)

\(0 \, tens \, + \, 4 \, ones \, = \, 10\)

\(4 \, tens \, + \, 0 \, ones \, = \, 20\)

\(4 \, tens \, + \, 0 \, ones \, = \, 4\)

\(1 \, ten \, + \, 5 \, ones \, = \, 15\)

\(5 \, tens \, + \, 1 \, one \, = \, 15\)

\(5 \, tens \, + \, 1 \, one \, = \, 17\)

\(1 \, ten \, + \, 5 \, ones \, = \, 13\)
