Count the clovers. Now choose the best answer. \(8 \, + \, 8 \, = \, x\)

\(0 \, tens \, + \, 8 \, ones \, = \, 8\)

\(8 \, tens \, + \, 0 \, ones \, = \, 15\)

\(8 \, tens \, + \, 0 \, ones \, = \, 8\)

\(0 \, tens \, + \, 8 \, ones \, = \, 11\)

\(0 \, tens \, + \, 8 \, ones \, = \, 8\)

Count the flowers. Now choose the best answer. \(3 \, + \, 3 \, = \, x\)

\(0 \, tens \, + \, 3 \, ones \, = \, 3\)

\(3 \, tens \, + \, 0 \, ones \, = \, 3\)

\(0 \, tens \, + \, 3 \, ones \, = \, 12\)

\(0 \, tens \, + \, 3 \, ones \, = \, 3\)

\(3 \, tens \, + \, 0 \, ones \, = \, 17\)

Count the records. Now choose the best answer. \(7 \, + \, 7 \, = \, x\)

\(0 \, tens \, + \, 7 \, ones \, = \, 7\)

\(0 \, tens \, + \, 7 \, ones \, = \, 16\)

\(7 \, tens \, + \, 0 \, ones \, = \, 20\)

\(0 \, tens \, + \, 7 \, ones \, = \, 7\)

\(7 \, tens \, + \, 0 \, ones \, = \, 7\)
